How Does The Dentist Whiten Your Teeth In The Office?

July 1, 2023

In-office teeth whitening is a cosmetic dental procedure usually done in a dentist’s office. The most common method for whitening teeth involves using a bleaching agent which removes stains and discoloration from the tooth enamel.

Typically, the procedure begins with thoroughly cleaning the teeth to remove any plaque or debris that could interfere with the whitening process. To track progress during treatment, the dentist or dental hygienist may take photos or impressions of the teeth.

The teeth will then be treated with a whitening gel or solution. The gel usually has a high concentration of hydrogen peroxide or carbamide peroxide, which aids in breaking down surface stains on the teeth.

A special light or laser may sometimes be used to activate the whitening agent and speed up the process.

The whitening gel is typically applied to the teeth for 15-30 minutes, during which time the dentist or dental hygienist may monitor the treatment’s progress. The additional gel may be used if necessary to achieve the desired level of whitening.

The teeth are rinsed and polished after the final application of the whitening gel to remove any remaining gel or debris. To help protect the teeth and reduce sensitivity, some dentists may also apply a fluoride treatment or desensitizing agent.

Overall, professional teeth whitening is a safe and effective method of whitening stained or discoloured teeth. While some patients may experience temporary sensitivity or discomfort during or after treatment, these side effects are usually minimal and may go away on their own after a few days.

How Long Do Teeth Whitening From A Dental Office Last?

The duration of a dental office’s teeth whitening results can vary depending on various factors, such as the patient’s diet, oral hygiene practices, and lifestyle habits. Professional teeth whitening can last anywhere between six months and two years, depending on the individual.

Because of the natural aging process, as well as exposure to certain foods and drinks that can stain the teeth, the effects of teeth whitening treatment may begin to fade gradually. Tobacco use and dark-coloured beverages like coffee, tea, and red wine can all cause your tooth to  tooth stain and discolour

To keep teeth whitening results, it’s critical to practice good oral hygiene habits like brushing and flossing,including visiting your dentist for routine cleanings and check-ups. Furthermore, avoiding or limiting foods and drinks that stain the teeth can help extend the treatment’s effects.

To help maintain the teeth whitening results, some dentists may also recommend at-home touch-up treatments. These treatments usually entail custom-fitted whitening trays and a lower concentration of whitening gel than is used in the dental office.
