Dental implants are a popular and effective restoration for lost teeth, if there’s enough bone present to support the implant. That might not be the case, however, because without the stimulation of the lost tooth, the bone may dissolve (resorb) over time. It’s possible, however, that you may need to re-grow bone in the back area of the upper jaw where your upper (maxillary) sinus is located.
Sinuses are air space cavities located throughout the skull. This feature allows your head to be light enough to be supported by your neck muscles. Inside each sinus is a membrane that lines your sinus cavities, nasal passages and other spaces. The maxillary sinus is located on each side of the face just below the eyes. Pyramidal in shape, the floor of the pyramid lies just above the upper back teeth.
A surgeon approaches the sinus through the mouth, with the objective of moving the sinus membrane up from the floor of the sinus. This is accomplished by placing bone-grafting material in the area. Over time the body uses the grafting material as a scaffold to produce new bone that then replaces the grafting material. The resulting new bone becomes the support for the implant.
If enough bone exists to stabilize an implant but not anchor it, then the surgeon can approach the sinus from the same opening that’s used for the intended implant site, insert the grafting material, and install the implant during the same procedure. If not, the surgeon creates a small “window” laterally over the teeth to access the sinus and insert the graft. The implant is installed a few months later after the new bone is created.
The procedure usually requires only a local anesthetic, although some patients may require additional sedation or anti-anxiety medication. After the surgery, you normally experience mild to moderate swelling and discomfort, about the same as having a tooth removed. All these symptoms can be managed with non-steroidal, anti-inflammatory pain medication and a decongestant for minor congestion in the sinus. We might also prescribe an antibiotic to help prevent infection.
Although this procedure adds another step and possibly more waiting time to implantation, it gives you an option you wouldn’t otherwise have — a life-like, effective replacement of your back teeth with dental implants.

When it comes to sensitive gums during pregnancy, Nancy O'Dell, the former co-anchor of Access Hollywood and new co-anchor of Entertainment Tonight, can speak from her own experience. In an interview with Dear Doctor magazine, she described the gum sensitivity she developed when pregnant with her daughter, Ashby. She said her dentist diagnosed her with pregnancy gingivitis, a condition that occurs during pregnancy and is the result of hormonal changes that increases blood flow to the gums. And based on her own experiences, Nancy shares this advice with mothers-to-be: use a softer bristled toothbrush, a gentle flossing and brushing technique and mild salt water rinses.
Before we continue we must share one important fact: our goal here is not to scare mothers-to-be, but rather to educate them on some of the common, real-world conditions that can occur during pregnancy. This is why we urge all mothers-to-be to contact us to schedule an appointment for a thorough examination as soon as they know they are pregnant to determine if any special dental care is necessary.
Periodontal (gum) disease can impact anyone; however, during pregnancy the tiny blood vessels of the gum tissues can become dilated (widened) in response to the elevated hormone levels of which progesterone is one example. This, in turn, causes the gum tissues to become more susceptible to the effects of plaque bacteria and their toxins. The warning signs of periodontal disease and pregnancy gingivitis include: swelling, redness, bleeding and sensitivity of the gum tissues. It is quite common during the second to eighth months of pregnancy.
Early gum disease, if left untreated, can progress to destructive periodontitis, which causes inflammation and infection of the supporting structures of the teeth. This can result in the eventual loss of teeth — again, if left untreated. Furthermore, there have been a variety of studies that show a positive link between preterm delivery and the presence of gum disease. There has also been a link between an increased rate of pre-eclampsia (high blood pressure during pregnancy) and periodontal disease. Researchers feel this suggests that periodontal disease may cause stress to the blood vessels of the mother, placenta and fetus.
