Summary
Quick summary of this article+

Worn tooth enamel does not grow back, but wear can be slowed and the tooth protected. The most common causes are erosion from acids (drinks, food, reflux), abrasion from hard brushing or habits, and attrition from grinding. Signs: yellower teeth, translucent edges that chip, sensitivity, shorter teeth. To slow it: fewer acid exposures, no brushing right after acidic food, a soft brush, fluoride toothpaste, treating reflux and a night guard for grinders. To rebuild: composite, veneers or oral rehabilitation, depending on the assessment. In Mooca, Dr. Cléo Salustiano (CRO-SP 170844) sees patients every day, from 8 a.m. to 10 p.m.

Worn tooth enamel does not grow back, because it has no cells that can regenerate. What can be done is to slow the wear, strengthen the remaining surface with fluoride and protect or rebuild lost areas with composite, veneers or other restorations, depending on the case. The most common causes are acids (from food, drinks or reflux), aggressive brushing and grinding or clenching.

In clinical practice, wear is usually noticed through indirect signs: teeth that look more yellow because the dentin shows through, thin translucent edges that chip easily, sensitivity to cold, shorter front teeth or small "steps" near the gums. Many people describe this as brittle teeth or teeth "breaking on their own".

Dr. Cléo Salustiano (CRO-SP 170844), a dentist in Mooca focused on cosmetic dentistry and rehabilitation, explains the types of wear, how to recognize each one and the treatment options.

What causes enamel wear?

Enamel wear has four main sources, which often appear together: erosion from acids, abrasion from brushing or habits, attrition from tooth-to-tooth contact (grinding) and lesions near the gums associated with bite forces. Identifying the cause is what makes it possible to slow the process.

Erosion: acids soften the enamel surface. They come from soft drinks, citrus juices, sports drinks, vinegar and acidic fruit consumed very often, and also from inside the body, as in gastroesophageal reflux or frequent vomiting. Teeth look smooth, rounded and sometimes translucent at the edges.

Abrasion: hard brushes, excessive force, back-and-forth scrubbing and very abrasive toothpastes wear mainly the area near the gums. Habits such as biting pens, opening packages or nail biting also wear specific spots.

Attrition: repeated contact between teeth, especially with grinding, flattens the tips and shortens the front teeth. The article worn-down teeth and oral rehabilitation shows what to do when this wear is already extensive.

Can tooth enamel be restored?

Lost enamel does not recover on its own, but a surface that has lost some mineral can be strengthened with fluoride, and parts already lost can be rebuilt or protected with dental treatment. So "restoring enamel" in practice means slowing the wear and replacing what is missing with restorative materials.

To slow wear: reduce how often you have acidic drinks and foods and, when you do, have them with meals; do not brush right after something acidic, giving saliva time to act; use a soft brush without excessive force; use fluoride toothpaste; treat reflux with your doctor; and wear a night guard if you grind your teeth.

To protect or rebuild: the dentist may recommend fluoride varnish for sensitivity, composite fillings to cover exposed areas, veneers to restore the shape and color of front teeth and, for generalized wear, an oral rehabilitation plan that considers the whole bite.

Toothpastes that claim to "rebuild enamel" can help with sensitivity and surface protection, but they do not bring lost enamel back. Consult a dentist to identify the cause before choosing any treatment. In Mooca, Dr. Cléo Salustiano sees patients every day, from 8 a.m. to 10 p.m., including Sundays and holidays.

Frequently asked questions: general dentistry

Can tooth enamel grow back?

+

No. Enamel has no living cells, so lost enamel does not grow back. A surface that has lost a little mineral can be strengthened with fluoride and saliva, and lost areas can be rebuilt with composite, veneers or other restorations, depending on the assessment.

How do I know if my enamel is worn?

+

Common signs are yellower teeth, thin or translucent edges, small chips, sensitivity to cold, shorter front teeth and steps near the gums. Since causes vary, the dentist examines the wear pattern to find its origin.

Why are my teeth chipping on their own?

+

Teeth that chip easily usually have enamel weakened by wear, grinding, large fillings or old cracks. It is not something to wait on: consult a dentist, because identifying the cause prevents bigger pieces from breaking and allows the teeth to be protected.

Do soft drinks and juice wear down enamel?

+

They can when consumed very often, because they are acidic. What matters most is how many times a day. Having them with meals, not sipping for hours and not brushing immediately afterwards helps reduce the effect.

Can toothpaste restore enamel?

+

Fluoride toothpastes and some specific products help strengthen the surface and reduce sensitivity, but they do not bring lost enamel back. They are part of prevention; rebuilding lost areas depends on in-office treatment.

What is the treatment for teeth with no enamel?

+

It depends on the extent. Small exposed areas can be covered with composite; worn front teeth may receive veneers; generalized wear calls for an oral rehabilitation plan that considers the bite. First, the dentist identifies and controls the cause.
