Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth... Done? Not quite — there's a whole world of enamel your toothbrush quietly misses every single day.
What Are Interproximal Cavities?
No matter how well you brush the visible surfaces of your teeth, you're leaving quite a bit of enamel untouched — the adjoining, or touching, surfaces of the teeth. These contact points are called the interproximal areas.
When bacteria in plaque are left undisturbed — especially with food particles available — they produce acids that gradually eat through enamel, creating a cavity that grows inward and downward, often invisible until significant damage has occurred.
Discovering Interproximal Cavities
A cavity between the teeth won't be as obvious as other cavities. Watch for any of the following — and remember that early-stage decay often has no symptoms at all, making regular check-ups essential.
Pain When ChewingPressure on the affected area can cause sharp or dull discomfort.
Temperature SensitivityLingering sensitivity to hot, cold, or sweet foods and drinks.
No Symptoms at AllEarly interproximal decay is often painless — only X-rays can reveal it. This is why routine exams matter.
Treating Interproximal Cavities
Treatment depends entirely on how far the decay has progressed. Catching it early is always the goal — the earlier we treat, the simpler and less invasive the solution.
Dental Filling
The most common treatment: decay is gently removed and the area is restored with a tooth-colored composite material that blends seamlessly with your natural smile.
Root Canal + Crown
If decay has reached the pulp chamber, a root canal removes the infection, and a crown protects and restores the tooth's full function.
Extraction
Reserved for cases where the tooth cannot be saved. Our team will always discuss implant or bridge options to restore your complete smile.
Preventing Interproximal Cavities
Prevention is straightforward — but it requires consistency and the right technique. These habits make an enormous difference when practiced daily.
Brush twice daily for two full minutes — morning and night — using gentle circular motions to remove plaque from all visible surfaces.
Floss once every day — this is the only way to remove plaque and food particles from between teeth where bristles simply cannot reach.
Ask about alternatives if traditional flossing is difficult — water flossers and interproximal brushes are excellent options for many patients.
Schedule regular check-ups and X-rays — routine exams catch hidden decay long before it becomes a bigger problem.
