A small hole in a molar is usually the early stage of tooth decay (cavity). At this stage, most cavities can be treated with a simple filling â no root canal is required unless the decay has reached the pulp (nerve) of the tooth. The only way to confirm this is with a clinical examination and, if needed, an X-ray.
Next Steps
Visit your dentist soon for a check-up. Get the cavity cleaned and filled to prevent it from spreading deeper. If X-ray shows that the decay is close to or has reached the nerve, then root canal treatment may be necessary.
Health Tips
Even small cavities can grow quickly if ignored. Brush twice daily with fluoride toothpaste, floss regularly, and reduce frequent sugary snacks/drinks to prevent new cavities.
