How do Teeth Become Discolored?

Teeth can become discoloured for a variety of reasons, including genetics, aging, and lifestyle habits. Some common causes of tooth discolouration include:

  • Aging – As we age, the enamel on our teeth naturally wears away, exposing the yellowish dentin underneath.
  • Food and drink – Certain foods and drinks, such as coffee, tea, red wine, and dark-coloured berries, can stain the teeth over time.
  • Tobacco use – Smoking or chewing tobacco can cause yellow or brown stains on the teeth.
  • Poor oral hygiene – Not brushing and flossing regularly can lead to the buildup of plaque and tartar, which can cause the teeth to appear yellow or brown.
  • Medications – Certain medications, such as tetracycline and some antihistamines, can cause tooth discolouration.

How Teeth Whitening Works?

Teeth whitening treatments work by using chemicals to break down the stains on the teeth, making them less visible. There are two main types of teeth whitening treatments: in-office treatments and at-home treatments.

In-office Teeh Treatments

In-office teeth whitening treatments are performed by a dental professional. These treatments use a higher concentration of whitening agents than at-home treatments, which allows for quicker and more dramatic results. In-office treatments typically involve the use of a light or laser to activate the whitening agent and accelerate the process. The entire treatment usually takes about an hour, and patients can see results immediately.

At-Home Teeth Treatments

At-home teeth whitening treatments are available over the counter at drugstores and supermarkets. These treatments usually involve the use of a whitening gel or strips that are applied to the teeth for a certain amount of time each day. At-home treatments typically take longer to produce results than in-office treatments, but they are less expensive and more convenient. It is important to follow the instructions carefully when using at-home treatments to avoid damaging the teeth or gums.

The Science Behind Teeth Whitening

Teeth whitening treatments work by using chemicals to break down the stains on the teeth. The most common whitening agents used in these treatments are hydrogen peroxide and carbamide peroxide. These chemicals work by releasing oxygen molecules, which react with the molecules that cause the stains on the teeth. This reaction breaks down the stains into smaller, less visible particles, making the teeth appear whiter.

The concentration of the whitening agent used in the treatment is an important factor in determining the effectiveness of the treatment. In-office treatments use a higher concentration of whitening agent than at-home treatments, which allows for quicker and more dramatic results. However, higher concentrations of the whitening agent can also increase the risk of tooth sensitivity and gum irritation.

It is important to note that teeth whitening treatments are not permanent. The effects of the treatment will gradually fade over time as new stains form on the teeth. The length of time that the results last will depend on factors such as the individual’s oral hygiene habits, diet, and lifestyle habits.

Conclusion

In conclusion, Teeth whitening is a popular cosmetic procedure that can help to improve the appearance of discoloured teeth. This procedure works by using chemicals to break down the stains on the teeth, making them less visible. In-office treatments use a higher concentration of whitening agent than at-home treatments, which allows for quicker and more dramatic results.
