Tooth Discoloration

Your teeth may change color due to stains on the surface or changes in tooth material. Dentists divide discoloration into three categories:

External discoloration - Occurs when the outer layer of the tooth (enamel) is stained with coffee, wine, cola or other beverages or food. Smoking can also cause external blemishes.
Intrinsic Discoloration - This is when the internal structure of the tooth (dentin) darkens or turns yellow. Causes include excessive childhood exposure to fluoride, use of tetracycline antibiotics by pregnant women in the second half of pregnancy, and use of tetracycline antibiotics in children 8 years of age or younger.
Age-related discoloration - This is a combination of extrinsic and intrinsic factors. In addition to stains caused by food or smoking, dentin will naturally turn yellow over time. The enamel that covers the teeth thins with age, which allows the dentin to see through. Chips or other tooth damage can also cause discoloration, especially if the pulp has been damaged.
In rare cases, children born with symptoms of dentine hypoplasia are gray, amber, or purple at birth.

Symptoms include stains on the enamel or yellow in the dentine.

No special test is required. The dentist can diagnose tooth discoloration by observing the teeth.

Some tooth discolorations can be removed by professional dental equipment cleaning, but many teeth stains are permanent unless the teeth are treated (whitened) with a bleaching gel.

Brushing your teeth after each meal will help prevent some stains. Dentists advise you to rinse your mouth with fresh water after drinking wine, coffee or other beverages or foods that can stain your teeth. Regular cleaning by dental hygienists also helps prevent surface stains.

It is sometimes possible to prevent intrinsic speckles caused by nerve or blood vessel damage in the interior (pulp) of the tooth by root canal treatment of the root canal, which removes the root canal before the organic material has the opportunity to decay and darken. However, teeth that are treated with root canals may turn black. To prevent children from appearing blemishes, avoid water containing high levels of fluoride. You can call the public health department to check the concentration of fluoride in your drinking water supply. Then consult your dentist.

Discoloration can often be eliminated by applying bleach to the tooth enamel. Using a technique called "energy bleaching," the dentist applies a photo-activated bleaching gel to make the teeth significantly white within about 30 to 45 minutes. Several follow-up treatments may be needed.

You can also use the bleach gel in your home and the dentist to give you oral care to eliminate discoloration. Bleach gels designed for home use are not as strong as bleach gels used by your dentist, so the process takes longer - usually 2 to 4 weeks. Whitening toothpastes can remove light stains, but in most cases they are not very effective.

If you have a root canal and the teeth darken, the dentist may smear bleaching material inside the teeth.

When a broken or severely damaged tooth or stain does not work on the bleaching of the teeth, the dentist may suggest covering the discolored area. This can be done with a composite adhesive material that matches the color of the surrounding teeth in conjunction with dental instruments. Another option is to obtain a veneer, which is a ceramic shell that covers the outer surface of the tooth. is one professional dental supplies website which supplies dental equipment in UK with competitive price and high quality.
