Replace the restoration before damage spreads

Why a lost restoration matters

A filling or crown protects the tooth underneath — once it's gone, that tooth is open to the bacteria in your mouth. Decay can advance surprisingly fast in an unprotected tooth, and the loss of structural support means the tooth can crack at unexpected moments. Most lost fillings and crowns are not painful emergencies, but they shouldn't sit unrepaired for weeks.

Why fillings and crowns come loose

• Cement breakdown over time. The dental cement that holds a crown isn't forever — most last 10 to 20 years before the bond weakens. A crown that suddenly falls off after 15 years is often nothing more dramatic than that.
• Decay underneath. Bacteria sometimes work their way into the margin between a filling or crown and the tooth, eventually undermining the bond. The crown comes off, and decay is visible underneath.
• Sticky food doing the pulling. Caramels, taffy, soft candies, fruit roll-ups — these can grab onto an aging crown or filling and tug it loose. Mostly a coincidence; usually the cement was already weakening.
• Grinding or clenching. Years of grinding put stress on every restoration in your mouth. Crowns under heavy bite forces fail earlier — which is why night guards extend the life of dental work substantially.
• Tooth fracture under the restoration. Less common, but if the tooth itself has fractured, the crown loses its foundation. This one needs a full evaluation — sometimes the tooth can be rebuilt and re-crowned, sometimes not.

What to do at home, in order

1. 1. Save the crown or filling. Put it in a small container or bag. Often it can be re-cemented at the visit — much cheaper than making a new one.
2. 2. Call us. 540-315-3725. We'll schedule a same-day or next-day visit during office hours.
3. 3. Protect the exposed tooth. If you can't get in same-day, pick up temporary dental cement at any pharmacy (Dentemp, Recapit, similar). Follow the package directions — usually a small bead pressed into the cavity or onto the inside of the crown, then the crown is pushed gently back into place.
4. 4. Eat soft and chew on the other side. Avoid sticky, crunchy, or hard foods until the restoration is replaced.
5. 5. Salt-water rinses after meals. Keeps the exposed tooth surface clean and reduces sensitivity.
6. 6. Ibuprofen if sensitive. 600 mg with food, every six hours, only as needed.

What NOT to do

• Don't use super glue or household adhesive. Toxic in the mouth, won't bond properly, and makes proper re-cementation harder for your dentist.
• Don't ignore it for weeks. Decay can advance surprisingly fast in a tooth that's lost its filling. A small fix today becomes a big one in a month.
• Don't chew on the exposed tooth. Without the structural support of a filling or crown, the remaining tooth can fracture under chewing forces.
• Don't try to "wedge" something into the hole. Wax, gum, or paper towel might block food temporarily but introduces bacteria and isn't a real solution.
• Don't throw away the old crown. Even if it looks worn, we can often clean it and re-cement it — saving the cost of a new one.

What happens at the visit

A focused exam and a digital X-ray of the affected tooth. We assess whether the old restoration can go back, whether there's decay or fracture underneath, and whether the tooth itself is still solid. If the old crown still fits cleanly over a healthy tooth, we re-cement it (one short visit). If there's decay, we clean it out and either re-cement the existing crown over the repair or make a new one (two visits, with a temporary in the interim). If the tooth has cracked or the decay is deep, a root canal or extraction may enter the conversation — and we'll walk you through every option before you decide.
