White Spots on Teeth

White spots can be an early sign of mineral loss from tooth decay, which may be stopped before a cavity forms.

[2]

The short answer

White spots from early decay may have no symptoms. As decay advances, the tooth can become sensitive to sweets, hot or cold drinks, or develop toothache.

What do white spots on teeth feel like?

What a changing spot may accompany
StagePossible experience
Early decayOften no symptoms[2]
Advanced decayToothache or sensitivity to sweets, hot, or cold[2]

What causes white spots?

Bacteria use sugars and starches from food and drinks to make acids. Repeated acid exposure removes minerals from enamel; a white spot can appear at that early stage.

How the process progresses
CauseChange in the tooth
Acid from bacteriaEnamel loses minerals[2]
Further mineral lossEnamel weakens and a cavity can form[2]

What relief is safe tonight?

Use fluoride toothpaste and clean between the teeth. Limiting sugary drinks and foods high in sugars or starches reduces repeated acid exposure while the spot is being assessed.

[2]

How are white spots checked?

A check may look for white, brown, or black staining, soft or sticky areas, and a cavity. An X-ray can show decay that is not visible on the surface.

[2]

How are white spots treated?

When decay is still before a cavity, fluoride can reverse it. Once a cavity has formed, the decayed tissue is removed and the tooth is restored with filling material.

[2]

How can you prevent more spots?

Brush twice daily with fluoride toothpaste, clean between teeth, limit sugary snacks and drinks, avoid tobacco, and keep regular check-ups and professional cleanings.

When does it need prompt attention?

Untreated decay can progress to a cavity, pain, infection, and tooth loss. Facial swelling or fever can accompany an infected tooth and needs prompt dental attention.

Frequently asked questions

Can a white spot turn into a cavity?

Yes. Continued mineral loss weakens enamel and can form a cavity; early decay may be stopped or reversed with fluoride.
