What is the direct answer?
Dental caries is tooth decay caused by acid from bacterial plaque, and it can affect anyone with susceptible tooth surfaces.
What does this question mean?
Caries begins when plaque bacteria use fermentable carbohydrates and produce acids that remove minerals from enamel. It can progress through enamel into dentin and eventually reach the pulp, where pain and infection may develop.
What can you do next?
Brush with fluoride toothpaste, clean between teeth, limit frequent sugary or starchy exposures, and arrange examinations to detect early mineral loss or a cavity. Treatment may involve fluoride support, a restoration, or pulp treatment depending on depth.
When should you seek dental care?
See a dentist for tooth sensitivity, a visible hole, a dark or chalky area, food trapping, swelling, or spontaneous pain. Facial swelling, fever, or swallowing difficulty needs urgent attention.
What should you ask the dentist?
Ask whether the lesion is an early mineral change or a cavitated area, how deep it is, and whether fluoride treatment, a filling, or pulp therapy is indicated.
