Can nipple biting ruin or rupture your saline breast implants?

Breast implants are isolated from the nipples, especially if they are placed in the sub muscular position. Biting on the nipples should not cause issues in most cases. On the other hand, if biting is sufficient to break the skin, an infection could develop and there would be a small chance that this could cause an implant infection.

Thank you for the question.  Implants are located far below your nipples, either below the breast gland or below the muscle.  I do not see how biting or injuring the nipple would result in damage to the breast implant itself.All the best,Dr Remus Repta

Typically your implant is fairly far away from the nipple. The good thing about saline is that damage is easy to tell because it will just decrease in size. Infection could be a risk which would show up as pain swelling and redness. If you are concerned see a reputable plastic surgeon in your area.
