Whitening is the most requested cosmetic dental procedure asked for by patients
What is professional whitening?
![Page 3: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/3.jpg)
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
![Page 4: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/4.jpg)
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
![Page 5: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/5.jpg)
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
![Page 6: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/6.jpg)
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
![Page 7: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/7.jpg)
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
![Page 8: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/8.jpg)
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
![Page 9: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/9.jpg)
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

General facts (not necessarily trays we can put this anywhere in the pwrpt if you want!)

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

Disadvantages:

![Page 32: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/32.jpg)
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
![Page 33: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/33.jpg)
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

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
![Page 37: Whitening Products By: Stella Grimm Samantha Fernung Natalie Glenn.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649d9d5503460f94a877c7/html5/thumbnails/37.jpg)
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
