Should the bottom of the crown on the implant be at the level of the gum or below the gum line?
I have crowns fused together but you can push a tooth pick all the way through from the outside to the inside between the posts. This allows food to catch at the gumline on the inside and I have to clean it out after I eat.
Should the crowns have good cusps at the edges like my natural teeth or rounded? ... Visitor from TX
In a perfect world, the implants should be a tiny bit below the gumline and food should not catch between the crowns.
It may be possible to remake the crowns over the implants to eliminate the food catch. Or, you could use an irrigating device like a WaterPik or Hydrofloss to be sure this area is cleansed well so the health of the implants is not negatively affected.
You might also seek a second opinion to see what another dentist thinks.
Implant crowns should bite the opposing teeth as strongly as natural teeth, and rounded cusps might have been designed to do this.
