Common Causes of Dark Spots on Teeth Without Cavities

Dark spots may be generated due to a number of reasons other than decay. The source aids in the right treatment. The most frequent reasons are as follows.

Surface Stains from Food and Drinks

Surface stains are the most common cause of dark spots. Coffee, tea, red wine, and cola cause discoloration. Pigmented foods like berries also stain enamel. These stains stay on the outer tooth surface. Professional cleaning usually removes them easily.

Tartar Buildup and Plaque Accumulation

Plaque hardens into tartar when not removed regularly. Tartar often appears yellow, brown, or black. It usually forms near the gumline. Tartar cannot be removed by brushing alone. Dental scaling is required for removal.

Natural Tooth Anatomy and Grooves

Some teeth have deep grooves or pits. These areas trap pigments more easily. Dark spots may appear even with good hygiene. These spots are not cavities but can resemble them. Sealants may help prevent further staining.

Fluorosis

Excessive amounts of fluoride during childhood result in fluorosis. It brings about white, brown or dark spots. The enamel is hard even when discoloured.Fluorosis is cosmetic, not harmful. Treatment focuses on improving appearance.

Medications and Medical Conditions

Certain antibiotics can discolor teeth, especially during development. Iron supplements may cause dark surface stains. Some medical conditions affect enamel color. These changes are not cavities. Cosmetic treatments can often improve appearance.
