A hole in my tooth
A visible hole in a tooth is commonly a cavity, but a broken filling, crack, or worn tooth can look similar.
The short answer
A hole is lost tooth structure from caries, fracture, erosion, or a failed restoration. Acids from plaque dissolve enamel and can reach dentin.

How can you protect a tooth with a hole?
Keep it clean, avoid hard foods on that side, and use fluoride toothpaste. Do not put aspirin or household materials in the opening.
Which symptoms mean a hole needs prompt dental care?
Book promptly for pain, swelling, food trapping, bad taste, fever, or night pain. Facial swelling or breathing difficulty is urgent.
What treatment might a hole in your tooth require?
Ask how deep the defect is and whether it needs a filling, crown, root canal treatment, or removal.
