What is dental whitening?
Dental whitening, also known as teeth whitening or bleaching, is a cosmetic dental procedure aimed at lightening the color of teeth by removing stains and discolorations. It enhances the appearance of teeth, giving them a brighter and more attractive look.

​

How does dental whitening work?
Dental whitening typically involves the application of a whitening agent, often containing hydrogen peroxide or carbamide peroxide, to the teeth. These agents break down and release oxygen molecules that penetrate the tooth enamel and target deep stains. This chemical reaction breaks apart the pigmented molecules, resulting in a lighter tooth color.

​

Is dental whitening suitable for everyone?
While dental whitening is effective for most people, it might not be suitable for individuals with certain dental conditions such as cavities, gum disease, or hypersensitivity. It's important to consult a dentist before undergoing any whitening procedure to determine if it's appropriate for your oral health.

​

What are the different methods of dental whitening?

There are several methods for dental whitening, including:
 

In-office Whitening: This involves a dentist applying a highly concentrated whitening gel to your teeth and using special lights or lasers to accelerate the whitening process.

At-home Whitening Kits: Dentists can provide custom-made trays and whitening gel for at-home use. These trays are worn over the teeth for a specific period, gradually whitening them.

Over-the-counter Products: There are various over-the-counter whitening toothpastes, strips, gels, and rinses available. These products usually contain milder whitening agents and may take longer to show noticeable results.

 

How long does each whitening method take to show results?
In-office whitening often provides noticeable results after a single session, which usually lasts about an hour. At-home treatments might take several days to a few weeks, depending on the frequency of use and the concentration of the whitening gel. Over-the-counter products generally take longer to achieve noticeable results compared to professional treatments.

​

Are the results of dental whitening permanent?
The longevity of whitening results varies. They are influenced by factors like diet, oral hygiene, and lifestyle habits such as smoking and consuming staining foods or drinks. Touch-up treatments or periodic use of whitening products might be necessary to maintain the desired level of whiteness.

​

What should I expect during and after the dental whitening process?

Some people may experience sensitivity or mild discomfort during or after the whitening process. This sensitivity is usually temporary and subsides within a few days. Dentists often recommend toothpaste formulated for sensitive teeth to help manage this discomfort.

​

Can dental whitening remove all types of stains?
Dental whitening is most effective against extrinsic stains (surface stains caused by factors like coffee, tea, or tobacco). Intrinsic stains (stains that occur within the tooth) caused by factors like trauma or certain medications might not respond as well to whitening. Your dentist can assess the type of stains you have and recommend the best treatment approach.

​

How can I maintain my whitened teeth?
To maintain the results of dental whitening, practice good oral hygiene by brushing and flossing regularly. Avoid or limit consumption of staining foods and drinks. If you smoke, consider quitting. Regular dental check-ups can help monitor the condition of your teeth and address any concerns before they become more noticeable.
