A sharp pain when you bite down? A jagged edge catching your tongue? You’ve likely chipped a back tooth. These teeth do the heavy lifting for chewing, and when enamel breaks, the tooth is exposed to temperature swings, bacteria, and further damage. Here’s a straightforward guide to diagnosing and fixing the most common chipped-molar scenarios you might run into.
Quick Fix Summary
Bite down pain-free, small chip? Grab over-the-counter dental wax, rinse with warm salt water, and schedule a same-week dentist visit to rule out pulp damage. If the tooth is sharp and cuts your tongue, use sugarless gum (or a piece of the wax) as a temporary shield until your appointment.
What’s Happening
Think of a chipped molar like a paper cut that never heals. Enamel doesn’t grow back, so that jagged surface lets hot, cold, and bacteria reach the living tissue inside. If the fracture goes deep—into the dentin or pulp—you might feel lingering pain or even develop an abscess within 48–72 hours Mayo Clinic, 2025. Tiny chips (less than a millimeter) usually don’t need nerve treatment, but bigger ones often do, even if you’re not hurting right now.
Step-by-Step Solution
Step 1: Pain Check and Visual Inspection
- Rinse with warm salt water (½ tsp salt in 8 oz water) to clean the area.
- Use a small dental mirror or your phone flashlight to spot the fracture. Look for a shiny gray line (enamel) or a dark brown/red line (exposed dentin).
- Gently probe with a clean cotton swab. If it snags or you feel a “crack” sensation, that’s a warning sign of deeper damage.
Step 2: Temporary Protection
- Superficial chip (feels smooth, no pain): Cover the sharp edge with a pea-sized dab of temporary dental cement (CVS, Walgreens, Amazon) or sugar-free gum. Keep it in place until you see the dentist.
- Moderate chip (dentin visible, mild pain to cold): Use the same temporary cement, but avoid chewing on that side.
- Large chip or pulp exposure (throbbing pain, pink spot): Don’t cover the exposed pulp—head to an emergency dentist within 24 hours.
Step 3: Imaging and Definitive Repair
Your dentist will likely start with a periapical X-ray (2D) or a cone-beam CT (3D, 45-second scan) to see how deep the crack goes and how close it is to the nerve American Dental Association, 2024.
| Chip Size | Typical Repair | 2026 U.S. Average Cost* | Duration |
|---|---|---|---|
| Minimal (1–2 mm) | Composite bonding | $150–$300 | 30–60 min |
| Moderate (3–5 mm) | Composite onlay or full crown | $350–$800 | 60–90 min |
| Deep (pulp involvement) | Root canal + crown | $1,200–$2,200 | 2–3 visits |
| Cracked cusp | Onlay or partial crown | $400–$1,100 | 90 min |

If This Didn’t Work
- Root canal flare-up (pain returns 1–2 days post-procedure): Call the office; they can prescribe a short course of antibiotics (amoxicillin 500 mg TID for 7 days) and schedule a follow-up.
- Crown falls out within 48 hours: Dry the tooth, place a dab of temporary cement, and return the same day for re-cementation.
- Crack extends subgingivally: The tooth may need extraction. Ask about a dental implant or bridge; as of 2026, the average fee for a single implant is $3,500–$4,800 American Academy of Periodontology, 2025.
Prevention Tips
- Replace your toothbrush every 3 months (or sooner if bristles fray). Brushing too hard with an old brush wears enamel faster than you’d expect.
- Use a night guard if you grind—ask your dentist for a hard-acrylic appliance; over-the-counter guards can actually fracture molars.
- Chew sugar-free gum with xylitol; it boosts saliva flow and helps neutralize acids that soften enamel ADA, 2024.
- Get a custom fluoride tray if you have dry mouth—fluoride varnish every 6 months thickens enamel and cuts chip risk.
