Tooth-colored fillings.

Most fillings today are composite resin — a tooth-colored material that bonds chemically to the enamel and dentin. We can color-match it to your tooth so closely that even you may have trouble seeing the filling once it’s placed. Functionally, composite is also stronger than the silver amalgam fillings of decades past, and the bonding process preserves more of your natural tooth.

When fillings are needed

The most common reason is a new cavity — decay that’s created a small pocket in the enamel and dentin that needs to be cleaned out and filled. Fillings are also used to repair small chips or wear patterns on front teeth, to replace old fillings that have broken down, and to seal cracks that have caught food and started causing sensitivity.

For very small cavities — particularly those caught at a routine exam before they’ve become symptomatic — the filling is a short visit. Twenty minutes for the procedure, including numbing. You go back to your day.

How long do composite fillings last?

With good home care and regular cleanings, ten to fifteen years is a reasonable expectation for most composite fillings. Larger fillings on chewing surfaces wear faster than smaller ones on front teeth. Heavy grinders may see fillings break down sooner; a nightguard helps significantly with that.

When a filling wears or starts to leak at the edges, we replace it before decay can take hold underneath. That’s another reason routine exams matter — we catch the breakdown before it becomes a bigger problem.

What about old silver fillings?

Older silver-amalgam fillings have been used safely for over a century, and there’s no medical reason to remove a stable one just because it’s silver. If yours are intact and sealing well, we generally leave them alone. We replace them when they show signs of leaking, fracturing the tooth around them, or when patients want a cosmetic upgrade and the timing is right.

What to expect at your appointment

Numbing the area takes a few minutes and is the only part most patients feel. After that, Dr. Agrawal cleans the cavity, places the bonding agent and composite material in thin layers (curing each with a small blue light), shapes the filling to your bite, and polishes it. You can usually eat as soon as the numbness wears off.
