I just had a veneer done, and I’m concerned about how it fits near my gum. My dentist says it’s okay because the gum covers it, but that doesn’t feel right to me. When I floss properly along the gumline, hugging the tooth with the floss, it slides under the veneer, and I can feel it there rather than just between the teeth.
I’m worried food and bacteria could get trapped there and cause a cavity near the root. Is this a big concern? Thanks. Callie from WY
Callie,

Porcelain veneers can close a tooth gap after you achieve good oral health
A veneer should follow the natural contour of your tooth at the gumline. When it doesn’t, a slight overhang can result. A smooth, flush margin helps keep the gums healthy and makes daily cleaning more effective.
What Are the Risks of Leaving an Overhang Untreated?
Overhangs create areas where plaque can hide. While decay beneath the margin can occur, gum irritation is far more common and often shows up first.
Patients with overhangs frequently experience:
- Tender or inflamed gums near the veneer
- Bleeding during flossing
- Ongoing difficulty keeping the area clean
Left alone, these issues can progress and compromise both the tooth and the gums.
Practical Steps You Can Take
Ideally, the veneer should be replaced so the margin fits correctly. Many dentists view this as part of delivering a proper result. If replacement isn’t possible with your current provider, another dentist may be able to correct the problem.
While you’re deciding on next steps, daily flossing is essential. Gently work the floss beneath the edge of the veneer to reduce plaque accumulation and calm the gum tissue.
