My dentist placed eight upper crowns in February 2025. After getting crowns, my gums began to swell and bleed, so my dentist removed and replaced them in September 2025. Unfortunately, the same gum problems returned, and I had the second set removed again about a week ago.
A periodontist recommended wearing temporary crowns for at least three months to allow my gums to heal. However, the temporaries feel like the original crowns, which makes me skeptical about the outcome. Another dentist told me the crowns are bulky and over-contoured near the gums and may not fit my natural teeth properly.
During a deep cleaning two weeks ago, the hygienist mentioned removing excess cement near the gumline. I’m now planning to have the crowns redone and have shared my X-rays with a dentist in Mexico and another in Costa Rica. If the new crowns are properly shaped and fitted, could that allow my gums to finally heal and the swelling to resolve? Thanks. Andrea from Boston
Andrea,
Without examining your crowns, we can’t say that they are over-contoured, but it’s a possibility. When crowns don’t follow the natural shape of a tooth, they often lead to gum inflammation, including redness, swelling, and bleeding.
Healthy teeth have contours that protect the gums. A well-made crown should closely replicate those contours to support long-term gum health.
Why Does Crown Contour Matter?
Dental crowns
When a crown is over-contoured, it can affect the surrounding gum tissue in multiple ways. These effects often work together to create ongoing irritation.
- The bulky shape places constant pressure on the gum tissue.
- The bulge creates a trap where food and plaque easily collect.
Both issues can inflame the gums and contribute to periodontal problems over time.
What Are the Effects of Excess Crown Cement Around a Tooth?
Residual cement is a known cause of persistent gum inflammation. The dentist who places the crown should remove all excess cement before you leave. Be cautious about dental tourism in another country and quick fixes after a frustrating experience. Careful, comprehensive correction—rather than the lowest-cost or fastest option—usually provides the best chance for long-term comfort and gum health.
