Not every case of tooth decay results from a dentist's negligence.
However, you may have grounds for a dental negligence claim if your dentist's failures caused or worsened the problem.
You may have a claim if:
Clear signs of decay were missed
- Your dentist failed to identify decay on an X-ray or during a physical examination that a competent dentist would have spotted.
Fillings were fitted poorly
- A filling was fitted incorrectly, leaving a gap where new decay could form (secondary caries). Or decay wasn't properly removed before the filling was placed.
Delayed treatment occurred
- Your dentist noted decay but waited too long to treat it, allowing it to worsen and require more serious intervention like root canal treatment or extraction.
