The size and condition of the remaining tooth structure determine whether we recommend a filling or a dental crown. At Mark Richardson, DDS, in Kalamazoo, MI, this is one of the most common questions patients ask after a diagnosis.
When a Filling May Not Be Enough
- The cavity covers more than half the surface of the tooth
- The tooth has a crack that extends beyond the decay
- An existing filling has failed, and there is not enough healthy structure left to support a new one
- The tooth has had a root canal and needs protection from fracture
Why the Amount of Tooth Structure Matters
A filling replaces missing tooth material. It does not reinforce the remaining tooth. When too much natural tooth is gone, the structure becomes thin and vulnerable to cracking under chewing forces. A tooth crown covers the entire visible part of the tooth. This restoration holds the remaining structure together and distributes bite forces more evenly.
What Your Dentist Looks for When Deciding
Dr. Richardson evaluates the size of the cavity, the condition of existing restorations, and the overall strength of the remaining tooth. X-rays help us assess what is happening beneath the surface. In some cases, a tooth that looks like it needs a filling turns out to need a crown once we fully remove the decay.
