2. Whitening is the most requested cosmetic dental procedure asked for by patients
What is professional whitening?

3. Your choices at the dental office are an in-office whitening or a “take home” professional whitening
Many different brands you can choose also
Whitening gel and Light sources/lasers

4. In-office whitening procedures usually a use hydrogen peroxide solution with a light source for activation
 “Power bleaching” can bleach your teeth in a single visit with peroxide and the light source

5. Hydrogen peroxide formula contains 15-38% peroxide
 In clinical studies, results show when the light source is added the results are better
 As much as a 2 shade improvement with the light source

6. Study by britesmile:
One group of subjects with hydrogen peroxide, one group with just the light, and then one group with combined peroxide and light.
96.6% with the combined product said it greatly whitened their teeth
39.3% with peroxide alone said moderately whiter
53.5% with light alone said moderately whiter also

7. Stains best removed from in-office whitening:
Aging, foods (coffee, red wine, sodas), tobacco use
Stains that are resistant to in-office whitening:
Inorganic stains, trauma which causes dentin to be darker, tetracycline antibiotics, overexposure to fluoride

8. Disadvantage: sensitivity
3 months after clinical study subjects were asked how sensitivite their teeth had become
Peroxide and light group and the peroxide alone group had a greater sensitivity than the light treatment group

9. Costs: in-office treatment $650 compared to $100 or less for over the counter treatments
This is not a permanent solution so follow up appointments are necessary also

*Existing problems such as cavities, tooth abrasion, attrition, exposed tooth roots, broken fillings, exposed dentin, have to be diagnosed and treated before bleaching (left untreated they would compromise whitening process)

18. General facts (not necessarily trays we can put this anywhere in the pwrpt if you want!)
Whitening should be accompanied with remineralizing techniques (fluoride and calcium phosphate applications)
Potential demineralization effects from a daily whitening regimen is comparable to drinking a cola beverage or glass of orange juice

20. Whitening Strips

21. What are Whitening Strips
Over-the-counter remedy that bleaches for a whiter smile
Compared to other whitening methods, consumer prefer strips because they are easy to use, comfortable to wear, are more cost effective and provide more consistent results

22. How do they work?
Apply a thin strip of plastic to the front of both the upper and lower teeth
One side of the plastic is coated with a bleaching agent called hydrogen peroxide
Once the plastic strips are in place, press them against the teeth for maximum contact
The strip is kept for a certain period of time depending on the concentration of hydrogen peroxide and the brand being used

23. Different Brands( Remembrandt versus Crest)
Differing brands will have different concentrations of hydrogen peroxide within their strips

24. Crest whitening strips
Examples: Crest 3D White Professional Effects, Crest 3D White Advanced
Uses 6.5% concentration of hydrogen peroxide in most of their products
Studies have supported that Crest Whitening strips remove both extrinsic stains (coffee, soda) and intrinsic stains (tetracycline)

25. Crest Whitening Effectiveness:
A study involving 25 candidates used Crest Whitening strips Advanced Vivid for 1 month.
Candidates were instructed to note any change in their tooth coloring on a daily basis for the duration of the study.
Candidates reported that they noticed a significant change within the first week and still better results within the preceding weeks

26. Before and After results:

27. Cost Effectiveness:

30. Advantages to whitening:
Extremely easy to use by using a step-by-step procedure
Convenient and comfortable to wear

More cost effective
Gives the wearer a whiter and brighter smile
Boosts self-esteem

31. Disadvantages:
There are several side effects that are caused by whitening products/whitening strips
The most two prevalent being tooth sensitivity and gingival irritation.

32. Tooth Sensitivity:
A layer of hard enamel protects the crowns of your teeth
A layer of cementum protects the tooth root under the gum line.
Gum tissue is a protective blanket that covers the tooth roots.
Underneath the hard enamel, or cementum, is the porous dentin which is made up of tiny openings, called tubules or channels

33. Tooth sensitivity cont.
Inside each tubule lies a nerve that comes from the tooths pulp
When the dentin loses its protective covering or is exposed, it may cause hypersensitivity and discomfort when you drink cold or hot liquids, eat sweet or sour foods, or when you breathe through your mouth
The nerves inside the tooth get stimulated causing everything from discomfort to a sharp, sudden, shooting pain deep into the nerve endings of your teeth

36. Gingival irritation:
Gingiva irritation is caused by the high levels of hydrogen peroxide in the whitening products touching the gingiva
This causes a burning sensation and is uncomfortable for the user

37. Other adverse effects:
Mucosal irritation, alteration of the enamel surface, and negative effects on restorations (not as common)
It is important to note that a woman who is pregnant should not use whitening products because, although there is no evidence of this, could cause damage to the fetus
