Tooth-Colored Fillings — Natural, Mercury-Free Restorations in Westlake, OH

With proper oral hygiene and regular dental checkups, composite resin fillings typically last 7 to 10 years — and many last longer. Longevity depends on the size and location of the filling, your bite forces, whether you grind your teeth, and how well you maintain daily oral care. Smaller fillings on less-stressed teeth tend to last the longest.

For small to mid-size cavities, composite fillings perform comparably to amalgam. Silver amalgam has a slight edge in raw durability for very large restorations on back molars that absorb heavy chewing forces. However, composite's ability to bond directly to the tooth — preserving more natural structure and reinforcing what remains — makes it the preferred choice for most modern restorations.

We don't recommend replacing intact, functioning amalgam fillings purely for cosmetic reasons — the removal process removes some healthy tooth structure along with the old filling. However, if an existing amalgam filling is cracked, leaking, showing signs of recurrent decay, or causing sensitivity, replacing it with composite is a sound clinical decision that also improves the appearance of the tooth.

No. Local anesthesia completely numbs the tooth and surrounding gums before any work begins — you won't feel pain during the procedure. Some patients experience mild sensitivity to hot and cold for a few days afterward, which typically resolves on its own. If sensitivity persists beyond a week or two, contact us so we can check the bite adjustment.

Common signs include tooth sensitivity to hot, cold, or sweet foods, a sharp or throbbing pain when biting down, visible holes or dark spots on a tooth, or food consistently getting stuck in a specific area. That said, many cavities are completely painless in their early stages — which is why regular dental exams with X-rays are the most reliable way to catch decay before it becomes a bigger problem.

Composite resin is more susceptible to surface staining than porcelain, but less so than your natural enamel. Coffee, tea, red wine, and tobacco are the most common culprits. Regular brushing and professional dental cleanings keep composite fillings looking fresh. If a filling does discolor over time, it can be polished or replaced.

A "mercury-free" dentist simply doesn't place new amalgam fillings — which describes most modern cosmetic practices today, including ours. A "mercury-safe" dentist goes further, using specialized equipment and protocols (like the SMART technique) to safely remove existing amalgam without exposing the patient to mercury vapor during the process. If you're interested in having old amalgam fillings replaced, we can discuss the safest approach for your situation.

Composite resin shrinks slightly — about 1.5% to 3% — as it's cured with the light. This shrinkage can create microscopic stress on the inner walls of the tooth, temporarily irritating the nerve. Using a careful layering technique (which we do) minimizes this effect significantly. Most post-filling sensitivity resolves within one to two weeks. If it doesn't, we'll reassess the bite and the restoration.

It's uncommon with modern bonding techniques, but it can happen — particularly if the filling is old, if you bite into something unexpectedly hard, or if new decay develops around the edges. If a filling comes loose, save it if possible, avoid chewing on that side, and contact us right away. We can re-bond or replace the filling, usually in a single visit.

Composite fillings are fully hardened by the curing light during your appointment — so the filling itself is ready immediately. However, we recommend waiting until the local anesthesia wears off before eating, so you don't accidentally bite your cheek, lip, or tongue. That's typically one to three hours after the procedure.
