INTRODUCTION
The oral mucosa (denture bearing mucosa) is not created to be covered or to carry prosthesis. Deviation from nature always results in changes in the tissues, which may be pathological.
Before the construction of new prosthesis, the supporting structures must be in a healthy condition.
A thorough examination of the mouth prior to construction of complete dentures is necessary to identify potential problem areas. Potential problem areas can be made with the aid of mounted diagnostic casts, intraoral radiographs and panoramic radiography. Read the rest of this entry »

When anesthetic has been used, your lips, cheek and tongue may be numb for several hours after the appointment. To prevent injury, avoid any chewing until the numbness has completely worn off.

Your gums may be sore for a few days. Rinse three times a day with warm salt water (add a tsp. of salt to a cup of warm water, then rinse, swish and spit) to reduce discomfort, if needed.
Use medication only as directed. Read the rest of this entry »

After an extraction or implant placement, it is important for a blood clot to form to stop the bleeding and begin the healing process — that’s why we ask you to bite on a gauze pad for 30 to 45 minutes after surgery. If bleeding or oozing continues after you remove the gauze pad, place another sterile gauze pad and bite firmly for another thirty minutes.
After the blood clot forms, it is important to protect it, especially for the next 24 hours. So, for the next 24 hours, DON’T: smoke, suck through a straw, rinse vigorously or spit. These activities will dislodge the clot, possibly causing bleeding to recur and slow down the healing process.
Limit yourself to calm activities for the first 24 hours, this keeps your blood pressure lower, which reduces bleeding and helps the healing process. Read the rest of this entry »
