Tooth Discoloration: Why Do Teeth Change Colour?
Have you noticed that your teeth are becoming yellow, brown, grey or darker over time? Tooth discoloration is common and can happen for many different reasons. Some stains are only on the surface, while others originate from inside the tooth and may require professional dental treatment.
At Parekh Dental Care, Mulund, we evaluate the cause of tooth discoloration before recommending teeth whitening or other cosmetic dental treatments.
πŸ”Ž Common Causes of Tooth Discoloration
1. Medicines & Antibiotics πŸ’Š
Certain medications can cause intrinsic tooth discoloration. For example, exposure to tetracycline antibiotics during tooth development in childhood can result in yellow, grey or brown discoloration. ADA
2. Injury or Trauma to a Tooth 🦷
A tooth that has suffered an injury may gradually become grey, brown or dark. Trauma can affect the pulp inside the tooth, so a darkened single tooth should be evaluated by a dentist rather than treated only with whitening.
3. Natural Aging ✨
As we age, enamel can become thinner and more translucent, allowing the naturally yellower dentin underneath to become more visible. This can make teeth appear increasingly yellow or darker. ADA
Other Common Reasons for Yellow or Stained Teeth
Tooth discoloration can also be associated with:
- β˜• Coffee and tea
- 🚬 Smoking and tobacco use
- 🍷 Coloured foods and beverages
- 🦷 Plaque and tartar buildup
- Certain mouthwashes, including prolonged use of chlorhexidine
-Certain chromogenic bacteria causes brownish lines aling the surface of tooth which come back again after cleaning.
- Dental cavities or changes within a tooth
- Fluorosis and other developmental conditions
- Older dental restorations
Surface stains and stains inside the tooth are treated differently, so identifying the type and cause of discoloration is important. ADA
πŸͺ₯ Can Tooth Discoloration Be Removed?
Sometimes, yesβ€”but the right treatment depends on the cause.
Professional dental cleaning can help remove many surface stains, while professional teeth whitening may lighten suitable natural teeth. Intrinsic discoloration, however, may need a different approach, such as dentist-supervised whitening, cosmetic bonding, veneers, or treatment of an underlying dental problem. ADA
It is also important to remember that crowns, implants and other tooth-coloured restorations do not whiten in the same way as natural teeth, so a dental examination is recommended before cosmetic whitening. ADA
