Good brushing doesn't eliminate the problem of acid reaching your teeth

Dental erosion occurs when acids from food, drinks or stomach contents—not acids produced by bacteria—damage the hard tissues of the teeth. Unlike surface staining or deposits, it can gradually remove enamel, the protective outer layer of a tooth.[1]

Careful brushing therefore does not rule out erosion. Both the bacterial film that brushing removes and the source of repeated acid exposure need attention. Toothpaste cannot make a tooth grow back into its original shape once that structure has been lost.[1][4]

When stomach acid reaches the teeth

When stomach contents travel up the esophagus into the throat or mouth, they can leave a sour taste. Repeated exposure also affects the environment around the teeth. Protection can be more difficult when saliva is not adequately washing away and buffering the acid.[1][2]

Not everyone with reflux develops the same amount of dental damage. The frequency and duration of exposure, saliva and eating habits all play a part. Assessment should work in both directions: checking the teeth of people with reflux, and exploring the habits and health history of people with erosion.[3]

Could reflux matter even without heartburn?

Heartburn and regurgitation are common reflux symptoms, but not every adult has both clearly. Reflux can also present in other ways, such as a persistent cough or hoarseness. These symptoms have several possible causes and cannot establish a diagnosis on their own.[2]

A dentist will look at the location and pattern of wear, decay and other causes of sensitivity, as well as habits such as frequent acidic foods or holding acidic drinks in the mouth. Medical assessment may be needed if reflux is suspected. Starting acid-suppressing medicine simply because your teeth are sensitive is not an appropriate approach.[1][3]

After a sour reflux episode, resist the urge to scrub

An unpleasant taste can make you want to brush immediately and scrub for longer. After acid exposure, however, it is better to rinse with water and adjust the timing and technique of brushing. For everyday care, use a soft toothbrush and fluoride toothpaste, and avoid aggressive scrubbing.[1][4]

These measures do not treat the underlying cause of reflux. Seek medical advice if symptoms recur or do not improve with changes to your habits. If you suspect a medicine may be involved, discuss it with the prescriber rather than stopping it yourself.[2]

Dental care and reflux management need to work together

Depending on the damage, care may involve reducing sensitivity or restoring lost tooth structure. Decisions depend on the remaining tooth, its function and your discomfort. Finding erosion does not automatically mean every affected tooth needs a crown or extensive treatment.[4]

Tell your dentist when regurgitation happens, whether you have repeated vomiting, what you drink regularly and which medicines you take. Checking whether acid exposure continues after teeth have been restored is important. Difficulty or pain with swallowing, persistent vomiting or unexplained weight loss also warrants timely medical assessment, independently of the dental problem.[2][3]
