Tooth Extraction

Of course no one wants to lose a tooth, but sometimes tooth extraction is the best option. If a tooth in severely infected or cannot be restored it may have to be extracted.

Portland dentist Dr. Austria can remove the most difficult teeth and we offer sedation dentistry to help make you comfortable during the procedure. Whether your tooth extraction is simple or a complex, we’ll work with you to develop a treatment plan that fully addresses any worries that you may have.

We believe that an educated and informed patient has substantially less anxiety about the procedure, and we make sure to include you in the decision making process.

We also offer treatment options including dental implants and dentures to help restore the natural beauty of your smile after your tooth extraction.

Wisdom Teeth Extractions

Third molars, commonly referred to as wisdom teeth, are usually the last four of 32 teeth to erupt (surface) in the mouth, generally making their appearance between the ages of 17 to 25. They are located at the back of the mouth (top and bottom), near the entrance to the throat. The term “wisdom” stems from the idea that the molars surface at a time typically associated with increased maturity or “wisdom.”

In most cases, inadequate space in the mouth does not allow the wisdom teeth to erupt properly and become fully functional. When this happens, the tooth can become impacted (stuck) in an undesirable or potentially harmful position. If left untreated, impacted wisdom teeth can contribute to infection, damage adjacent teeth, and possibly lead to cysts or tumors.

Dental Bone Grafting

Periodontal disease is the leading cause of bone loss in the oral cavity, though there are others such as ill-fitting dentures and facial trauma. The bone grafting procedure is an excellent way to replace lost bone tissue and encourage natural bone growth.

Bone grafting is a versatile and predictable procedure which fulfills a wide variety of functions. A bone graft may be required to create a stable base for dental implant placement, to halt the progression of gum disease or to make the smile appear more aesthetically pleasing.

Ridge Modification

Ridge modification is an effective procedure for treating deformities in the upper and lower jaws. These deformities can occur as a result of periodontal disease, trauma, injury, wearing dentures, or developmental problems. Such defects can leave insufficient bone for the placement of dental implants and an additional unattractive indentation in the jaw line adjacent to the missing teeth.

During the ridge modification procedure, the gum is lifted away from the ridge to fully expose the defect in the bone. The bony defect can be filled with bone graft material which can help regenerate lost bone, or a bone substitute. Finally, the incision is closed and several months of healing will be required. Depending on the case and type of implant and procedure, a dental implant may be placed during the ridge modification procedure or when healing is complete; much depends on the precise condition of the bone. Ridge modification improves the cosmetic appearance, functionality of the mouth, and the chance of enjoying dental implants for many years.

Ridge Augmentation

After a tooth is lost, the gums and jawbone can develop an indentation where the tooth once was, making it difficult to replace a tooth for a natural look. Ridge augmentation is a procedure required to replace the natural contour of the gum and jaw, leading to the success of placing dental implants, and other restorations.

Dr. Austria provides simple ridge augmentation to fill in this indentation through a surgical bone grafting procedure where the empty space is replaced with bone and the gums are sutured. After the area has healed, the result can allow for a replacement tooth that is more natural looking and easy to clean.

Sinus Augmentation

A dental implant is essentially an artificial tooth root which is attached to the jaw bone. Eventually, a replacement tooth or bridge will be firmly fixed to this root, restoring complete function to the tooth. The key to a successful and long-lasting implant is the quality and quantity of jawbone to which the implant will be attached. If bone has been lost due to injury or periodontal disease, a sinus augmentation can raise the sinus floor to allow for new bone formation.

In the most common sinus augmentation technique, a tiny incision is made near the upper premolar or molar region to expose the jawbone. A small opening is cut into the bone and the membrane lining the sinus on the other side of the opening is gently pushed upward. The underlying space is filled with bone graft material and the incision is closed. The bone which is used for this procedure may be from your own body or from a cadaver. Sometimes the dentist might use synthetic materials which can also stimulate bone formation. The implants are placed after healing has occurred; this will depend on the individual case. Sinus augmentation has been shown to increase the success of dental implant procedures.

Bone Regeneration

Dental implants and other restorative procedures depend on the jawbone being sufficiently strong and thick. When periodontal disease has taken hold, the jawbone may have become too thin to successfully support an implant. Natural bone regeneration (or bone grafting) is one of the best ways to promote growth and thicken the jawbone.

Initially, bone grafting material is obtained from elsewhere on the body or from a bone bank. The gums are gently pulled back, and an opening is made in the jawbone where the grafting material will be packed in tightly. A membrane is used to maintain the shape of the new bone, and tissue stimulating proteins and a platelet-rich growth factor may be applied to promote faster healing. The surgical site will be sutured and packed with protective material. The bone will naturally regenerate and become strong enough to eventually support an implant.
