1994). Ninety-five per cent of patients are genuinely glad they went through the procedure and 97% recommended the procedure to their friends (Leonard 1998). In the latter study most of the teeth were associated with previous trauma, and it is not known whether the trauma predis-posed the tooth to the resorption or whether it was caused by the effects of the whitening agent. become green around the margins. Although patients with severe wear on their teeth may request whitening, further restorative dentistry may be more appropriate. Typical at-home products include gum and dental strips. Toothpastes have become more specialized and sophisticated in the last decade (Koertge et al. Each of your teeth is made up of an inner dentin layer and a hard outer enamel layer, which protects the teeth… well as the stain. There is also the possibility of an allergy to the whitening materials or to the tray plastic material. 1997). Hasson et al. Composition of composites that gives and match the color of the tooth… First, your dentist will place a protective coating on the gum tissue and lips to protect them from the harsh whitening ingredients. 1991). This effect is most commonly noticed on lower canines, and patients are often concerned that their teeth are whitening unevenly. Resin tags in whitened enamel are less numerous, less defined, and shorter than those in unwhitened enamel (Titley et al. Caution should be taken to avoid addition of these chemicals to commercial preparations intended for tooth whitening. The manufacturers (Procter & Gamble, Cincinnati, OH) claim that the strip holds the gel in place to whiten the teeth both extrinsically and intrinsically and provides a uniform controlled application of gel. There was no significant difference between the two materials tested, which were Opalescence and NiteWhite. Teeth whitening trays include one or more mouthguard-like trays with a gel-based whitening solution. The whitening strips and products with high concentrations of hydrogen peroxide caused more users to report tooth sensitivity. Teeth whitening pens Another trend in over-the-counter teeth whitening is whitening pens or swabs. Today it is also seen … Studies using 10% CPS also showed that the bond strength of composite to etched enamel was reduced (Cvitko et al. 2. Whitening sugarless chewing gum helps to remove food residue after eating. Pulp penetration during whitening varies significantly among commercial 10% carbamide peroxide whitening products (Thitinanthapan et al. Carbamide peroxide eventually breaks down to water, oxygen, urea, carbon dioxide, and ammonia (Figure 3.8). All rights reserved. Erosive dentin lesions may not whiten sufficiently, and it may be inappropriate to whiten areas of deep erosion. 2009). (1991) have shown that there is a reduced bond strength of composite to enamel immediately after whitening with a 35% solution of hydrogen peroxide. It's important to have proper oral hygiene habits before any teeth whitening treatment. What causes discoloration of teeth… Of the first category, 100% of patients experienced tooth lightening compared with 80% of those with brown fluorosis and 75% of the tetracycline patients. Yellow stains are the easiest to whiten. Brightening and whitening teeth have become the number one aesthetic concern for many people. as closely as possible, the risk of enamel microhardness decrease as a result of whitening treatments seems to have been reduced. The combination of a hard toothbrush and an abrasive toothpaste has been recognized as creating further tooth wear problems. Sodium perborate has been banned in Europe for use in tooth whitening because it is considered to be fetotoxic and cytotoxic. - Whitening products are found in many everyday items like as toothpaste, fluoride, and mouth raises, also Peroxide-based solutions are used whitening products. Table 3.5  Properties of the ideal whitening agent. The calcium/phosphate ratio of dentin was significantly decreased by whitening with 30% hydrogen peroxide and 10% carbamide peroxide in a study by Rotstein and colleagues (1996). The introduction of whitening toothpastes has been very rapid. The paste toothpaste is more abrasive than the gel toothpaste. These involve the application of the whitening product to the teeth with a small applicator … 4H2O, molecular weight 153.81). Table 3.6  Factors affecting rate of color change, •  Frequency with which solutions are changed, •  Amount of time for which the whitening agent is in contact with the tooth, •  Original shade and condition of the tooth, •  Location and depth of discoloration (Howard 1992), •  Degradation rate of the material (Matis et al. The active ingredients in whitening strips vary, but many use … Get a list of all ADA-Accepted at-home bleaching products. Rather, these toothpastes target the surface of your teeth with a variety of substances, including abrasives and the chemical blue covarine. A brightness index derived from computer analysis of digitized images may be useful for monitoring effectiveness of whitening (Bentley et al. 1991) and disrupts the surface (Haywood 1999a). Dentists should encourage their patients to stop smoking for general health improvement and to enroll in a smoking cessation program. Most scanning electron microscopy studies of enamel surfaces treated with CPS whitening agents have shown little or no change in morphology (see Figures 3.16–3.18). These results are consistent with calcium loss from enamel after 2-min exposures to carbonated cola, orange juice, apple juice, or diet carbonated cola (Grobler et al. Further clarification of this is required. Existing amalgams may change color from black to silver (see Figure 3.19). 2008). This is very rare. Other luting cements may also be affected. Second, the chewing gum's whitening ingredients can coat the teeth to prevent staining. 1998a). There is no significant difference in the whitening efficacy of different concentrations of the material used during whitening treatments. 1991). 1991, Godwin et al. A systematic review conducted by Attin showed interesting results. The European Commission’s Scientific Committee on Consumer Safety is of the opinion that sodium perborate and perboric acid can be considered as “hydrogen peroxide”–releasing substances and thus are covered by entry 12 of Annex III of the Cosmetics Directive 76/768/EEC (Council of European Dentists 2014). Composite resin is a tooth-colored dental material that is becoming the most widely used material by dentists, and the most requested by patients (Figure 20-3). (1991) the patients who experienced transient tooth hypersensitivity after week 2 had overloaded their trays. Try these best teeth whitening products … 1991, Baughan et al. There has not been that much clinical research conducted on these products, which concerned the American Dental Association Council on Therapeutics (1994). Whitening toothpastes don’t use carbamide peroxide. The whitening process is thus dependent on the time for which the whitening agent is in contact with the tooth. It works best at temperatures over 55°C. Have questions about your smile? Carbamide peroxide is a bifunctional derivative of carbonic acid. Studies by Torneck et al. Fired porcelain showed a slight change after being immersed in the whitening gels for three 2-hour periods a day for 5 weeks (Hunsaker et al. Depending on the manufacturer's instructions, whitening strips can be used up to 30 minutes a day for up to two weeks for a noticeable whitening result. This is because of the anatomy of the enamel and dentin microstructure. However, whitening treatment at your dentist's office can have longer-lasting results. This hardness reduction may arise as a result of degradation or denaturation of enamel matrix proteins by the peroxide oxidation (Elfallah and Swain 2013). •  It can break up a large macromolecular stain into smaller stain molecules, which are expelled to the surface by diffusion. This chapter will discuss the different materials that are used for tooth whitening treatments (Tables 3.1 and 3.2). The whitening period may need to be extended to 6–10 weeks to achieve significant lightening. The urea that is present in the gels assists with wound healing and contains a soft tissue protectant. (2013) showed that compromised bond strength to whitened enamel was immediately restored with the application of antioxidant gel sodium ascorbate and exposure to human saliva in situ for at least 7 days. Tooth color is primarily determined by the dentin and can be changed by whitening treatments. Patients with known sensitivity or allergy to any of the ingredients should not use the whitening agent. The researchers observed that canines responded better to a 16% solution than did the central and lateral teeth. 1991). All trials were, however, short term, and most were judged to be at high risk of bias and were either sponsored or conducted by the manufacturers. (1994), at 1.5 years after treatment 74% of patients who had responded to home whitening were satisfied with the shade of their teeth. It can laterally diffuse through the tooth and into the pulp within 5–15 minutes. CPS has been incorporated into a chewing gum with inhibition of plaque formation (Moss 1999). This is related to the whitening potential of the Carbopol slow-release oxygen agents, which can remain active for 10 hours during the whitening treatment (Matis et al. Internal whitening of endodontically treated teeth has been shown to result in greater leakage of composite restorations immediately after completion of internal whitening (Barkhorder et al. Each strip is worn for 30 minutes, removed, and discarded, and the procedure is performed twice a day for 14 days. Although there have been few reports of effects on amalgam restorations, studies (Hummert et al. 1990). True or False Amalgam is safe' affordable and durable material used predominantly to restore anterior teeth. 1999; see Figures 3.8 and 3.9). 1992). Nevertheless, more in situ and in vivo studies are needed to verify this observation (Attin et al. The most effective products have been hydrogen peroxide and carbamide peroxide. Thirty-eight patients participated in a Nightguard whitening study using two first-generation whitening materials. All these techniques rely on adequate adhesion of the composite to the enamel. This effect is dependent on the type of dental amalgam used (Rotstein 1999, personal communication). 1998), but is thought to be the opposite of the whitening procedure. The effect is primarily the superficial cleansing of the restoration and a lightening of the underlying tooth structure and not an intrinsic color change of the restorative material itself. Just like whitening strips, teeth whitening trays may have to be used multiple days a week for up to two weeks for the best results. It may be more appropriate to wait for 2 weeks before placing the composite restoration and to place a glass ionomer restoration directly into the access cavity immediately after completion of the whitening treatment to prevent the reduction in bond strength. As a whitening agent, sodium perborate is used with organic activators such as tetraacetylethylenediamine (TAED) to allow the use of sodium perborate at lower temperatures. Treatment with sodium ascorbate gel for 60 minutes may be recommended if patients cannot wait for at least 7 days for adhesive techniques to be performed. The penetration of oxygen inside the tooth gives the tooth a whiter appearance. 1993). Ask the Colgate Chatbot! Miranda et al. Using Opalescence whitening material, Matis and coworkers (1999) have shown that carbamide peroxide degrades in an exponential manner after the first hour and that the degradation rate is higher in areas closer to the tooth structure. Activated charcoal is the new fad in the natural health market. Whitening was terminated at that point with immediate effect. Mild to moderate tooth sensitivity and gingival irritation were the most common side effects. The studies using CPS have shown promising results. Discuss the composition and variety of tooth-whitening products. Learn about the four different types of teeth whitening below. There are some key points that you must keep in mind while choosing the best over-the-counter teeth whitening products – The concentration of the bleaching agent – hydrogen peroxide is one of the most popular bleaching agents used in tooth whitening products. This is the longest post-treatment clinical study published. 1991). It is not intended to be a substitute for professional advice, diagnosis or treatment. However, a study using a whitening/remineralization cycle showed that 10% carbamide peroxide treatment significantly decreased enamel hardness. You can easily swap your regular toothpaste and mouthwash for whitening toothpaste and mouthrinse. Upper teeth whiten more quickly and have fewer side effects than lower teeth. The overzealous use of abrasive toothpaste will cause the removal of enamel as well as the stain. A dark black crack line on the central incisors caused by grinding and smoking may not be lightened with whitening (see Figure 3.12). The free radical is very reactive and has great oxidative power. However, there is no scientific literature about this, and these are purely manufacturers’ claims. The researchers also showed that there was a change in the fracture toughness of the enamel (McCracken and Haywood 1996). Occasionally an allergy to hydrogen peroxide may be noted. No effect on gold has been reported. Best results were obtained with exposure to human saliva in situ for 14 days. Dentin bonding may be altered after whitening (Della Bona et al. What are tooth stains anyway? the light or heat source may cause an adverse effect such as necrosis of the pulp of the tooth treatment may take 6 applications for desired results time varies between the different products ranging anywhere from 30-60 mins whitening … The residual oxygen in the whitened tooth surface also inhibits the polymerization of the composite resin (McGuckin et al. 1991), and another study showed that surface hardness was unaffected by whitening (Nathoo et al. 4. Whitening toothpaste can contain mild abrasives to gently remove stains on the surfaces of the teeth while brushing. (guide to measure success, show whitening … There are even special whitening toothbrushes available to polish teeth without abrasion using special condensed bristles. A clinical trial (Leonard et al. It has been tested for use as an irrigant or lubricant in root canals and as an adjunctive to sodium hypochlorite (Stindt and Quenette 1989). There may be a decrease in the translucency of the tooth. First, chewing gum after meals stimulates saliva production to rinse away bacteria and food. 1998) with many designed to perform either therapeutic or cosmetic functions. Provisional restorations such as those using intermediate restorative material (IRM) may be affected by hydrogen peroxide (see Figures 3.20 and 3.21). Pulp penetration can occur within 5–15 minutes according to studies by Cooper et al. The majority of the literature and research indicates that the use of 10% carbamide peroxide for dentist-monitored home whitening is an effective and safe way to lighten discolored teeth (see Figure 3.1). Participants were instructed to wear the guard at night or during the day for 2–4 hours for 6 weeks of total treatment time. Any factor compromising adhesion can affect the aesthetics and longevity of the bonded restoration (Cvitko et al. However, at the end of the 2-week trial period, there were no statistically significant differences among the 5%, 10%, or 16% solutions. Patients should be informed of this phenomenon because they tend to think that the whitening is regressing; in reality the teeth are equilibrating to the new actual shade (Haywood 1999b). If you work with your dentist, they will take an impression of the teeth, and then your tray is made to fit your mouth. and oxygen and for brief periods forms the free radical HO2• perhydroxyl. 1997). In a tooth whitening method, a whitening composition is applied to at least one tooth. Nevertheless, more in situ and in vivo studies are needed to verify this observation (Attin et al. The viscosity also improves adherence to the tooth. Take care of any cavities or gingivitis. Your dental professional can make recommendations and advise you on the best whitening treatment for you. However, the bond strength will improve if etching and bonding are delayed for 1–2 weeks postwhitening (Titley et al. However, this amount is small and the results may not be clinically significant. Whitening is a dental procedure- help patient select best tx option 3. However, clinically this may be difficult to achieve because patients may not tolerate the application of ascorbic acid to the teeth for such a long period of time. Speak with your dentist before using any teeth whitening treatment to ensure the safest way to achieve a whiter smile with the best possible results. They may be used to maintain white teeth after whitening. 1999). ... discuss options with your dentist and look for one with the ADA Seal of Acceptance. The reduction of hardness may reflect the loss of mineral from enamel, which could also result in reduced wear resistance (Seghi and Denry 1992). Give the properties of temporary restorative materials and their application in the restoration of teeth. •  Not dehydrate the oral tissues or teeth. Other restorative treatment may be more appropriate for these patients (see Figure 3.15). Keeping whitening gum with you for after meals may help maintain results after your whitening treatment. This process usually features a higher concentration of whitening ingredients than you'll find in products in the store. Older teeth, because of the more complex dentin structure, take longer to lighten (see Figures 3.1, 3.10, and 3.11). Dehydration of the hard tissue is less likely to occur with hydrogen peroxide treatment. These materials have different properties. Encourage the patient to refrain from smoking during treatment (Larson 1990). demand for esthetics, has produced a tremendous market for tooth whitening. 1999). Longer treatment times may thus be advisable—that is, the agent needs to be active for extended periods of time; to get maximum use out of the whitening agent, it is preferable to sleep with the tray in position. The toothpaste provided with the kit may be abrasive to the tooth surface (Jay 1990). Carbopol enhances the viscosity of the whitening material. It appears that lateral incisors take up the whitening product most quickly. This may be a result of the copper content of the amalgam (Haywood 2007). In a study by Scherer et al. With extension of the treatment time, the efficacy rate for patients with tetracycline staining improved to 90% (Haywood et al. • List the properties of dental materials and ways that they affect their application. The oxidants react with the chromophores, which are the color radicals, to cleave the double bonds. Regression occurs over a longer period because some of the previously oxidized substances may become chemically reduced and cause the tooth to reflect the old discoloration or the enamel may become remineralized with the staining molecule of the original stain (Lyons and Ng 1998). No patient felt the need to have the teeth re-treated as a result of color regression. In-office whitening treatments at your dentist's office can have excellent results. Plus, versatility is the name of the game, with plenty of formats to choose from—toothpaste, strips, pens, and more—to fit any preference. 1998) during the first hour after treatment. Before we get into the details of tooth-whitening, let's take a minute to meet the enemy. It reduces plaque adherence and accumulation and therefore has been used for treatment of periodontitis, oral hygiene (Stindt and Quenette 1989), reduction of gingivitis, reduction of caries rate, and aphthous ulceration (Tse et al. 2006) that assessed 416 articles on tooth whitening noted that strips (5.5% to 6.5% hydrogen peroxide) are more effective than gel in tray with 10% carbamide peroxide (mean difference 1.82; 95% confidence interval [CI] 0.26–3.38). 1996, Kelleher and Roe 1999). Some parts of the tooth may be difficult to whiten. One arch at a time! The shade never reverts to the original shade. A study by Scherer et al. A lower concentration of carbamide peroxide will also work, but it will take longer. It was noted that the more times the whitening tray was replenished, the greater the likelihood of sensitivity. Peroxide solutions flow freely through the enamel and dentin and into the pulp owing to the porosity and permeability of these structures (McEvoy 1989). Whitening on lower teeth can be slower. At 3 years after treatment 62% were satisfied with their color. Table 3.7 lists the possible side effects. Keep records (before/after photos) 5. • Describe the factors that affect how dental … The bleaching products … 1999) evaluating color stability after 54 months of tetracycline-stained teeth that were treated with 10% carbamide peroxide and extended whitening times showed that it is possible for the color to remain stable for 54 months after whitening treatment.
