After the implant is placed, you need to give your teeth sufficient time and care so they can heal without developing infections. Harmful habits that can cause this include smoking and chewing tobacco. Plus, don't apply any heat to the face until you are allowed to by your dentist. It may otherwise make the swelling worse and prolong healing.
Additionally, avoid drinking through straws. The pressure required may dislodge a blood clot covering the wound, which can lead to bleeding and cause infections.
