Restorative Dentistry
A filling removes decay or minor damage and restores the tooth's shape, without removing more of the natural tooth than necessary. For San Ramon patients, catching a cavity while it's still small is usually what keeps a simple repair simple.
What it is
A filling repairs a tooth after decay or minor structural damage has been removed. The dentist cleans out the affected area, then fills the resulting space with a material shaped to match the tooth's natural contours.
Unlike a crown, a filling doesn't cover the entire tooth — it restores the specific area that was damaged, leaving the rest of the healthy tooth structure alone.
When it may be appropriate
A filling tends to be the right tool when decay or minor damage is limited enough that a good amount of healthy tooth structure remains. Catching a cavity earlier generally means a smaller area needs to be treated — one more reason regular exams matter, beyond comfort.
Not every cavity only needs a filling. When decay is extensive, a crack runs deep, or too little healthy structure remains to support a filling, a crown may be the more durable answer. If the pulp inside the tooth is infected or significantly inflamed, root canal treatment may need to be considered before the tooth is restored. Which category a tooth falls into is something the dentist determines after actually examining it.
Why the exam comes first
Before recommending a filling, the dentist evaluates how deep the decay goes, how much healthy tooth structure remains, and whether the tooth's biting surface can hold up under normal chewing force once repaired.
That evaluation is what determines whether a filling is enough, or whether a more protective restoration makes more sense — a judgment made after a look at the actual tooth, not assumed in advance.
Benefits and trade-offs
A filling preserves more of the natural tooth than a crown. Many fillings can be completed in a single visit, depending on the tooth and the extent of the repair, and the treatment stops active decay from spreading further into the tooth.
A filling doesn't add strength to a tooth the way a crown does, and a tooth with a large filling can still be more prone to future fracture than one that was never damaged.
What patients can expect
After numbing the area, the dentist removes the decayed or damaged portion of the tooth, then places and shapes the filling material to restore the tooth's natural contour. The bite is checked before you leave, so the filling feels right when you chew.
Because there's typically no lab-fabricated piece to wait for, many fillings can be completed in a single visit, depending on the tooth and the extent of the repair.
Long-term considerations
A filling can wear down, chip at its edges, or develop a small gap where new decay can start underneath it, particularly after many years of normal use. Regular exams are what catch this early, while the fix is usually still another filling rather than something larger.
If a tooth has needed the same filling replaced more than once, or the remaining structure is looking thin, that's often the point where a conversation about a crown is worth having.
A consultation is a conversation, not a commitment. If it turns out to be nothing, we'll tell you that too.
