Early decay
Early tooth decay may appear as a chalky or brown area and can sometimes be arrested before a cavity needs a filling.
The short answer
Early tooth decay may appear as a chalky or brown area and can sometimes be arrested before a cavity needs a filling. Once bacteria create a cavitated hole, cleaning and restoring the damaged structure may be needed.
How do plaque acids begin the process of tooth decay?
Decay begins when acids from bacterial plaque dissolve minerals from enamel. Early mineral loss can make enamel porous, while continued mineral loss can reach dentin and produce sensitivity or a visible cavity.
What daily steps can reduce early tooth decay?
Brush twice daily with fluoride toothpaste, clean between the teeth, and reduce how often sugary or acidic foods and drinks contact the teeth. A dentist can examine the area, use radiographs when indicated, and prescribe fluoride or place a filling according to depth.
Which new tooth changes need a dental examination?
Book an examination for a new white, brown, or black mark, food trapping, sensitivity, or a rough edge. Pain, swelling, a broken tooth, or spontaneous nighttime discomfort needs prompt assessment.
How can the dentist tell whether decay is active?
Ask whether the lesion is active, whether it has formed a cavity, and whether monitoring, fluoride treatment, sealant, or a restoration is appropriate. Ask how to improve plaque control at that exact site.
Frequently asked questions
Can early decay heal?
Mineral loss can be arrested or partly repaired when the surface remains intact and fluoride and plaque control improve.
Does a brown spot always mean decay?
No. Staining, developmental enamel changes, and decay can look similar, so examination is needed.
