For most people, replacing missing front teeth takes a higher priority over missing back teeth. The reason is obvious: others can see those missing in front, but not necessarily those in the back.
From a functional view, however, you should still consider replacing missing back teeth. Not only will it improve your chewing ability, it may also prevent a chain reaction of negative effects to your remaining teeth.
Teeth are held in place in the jawbone by a membrane called the periodontal ligament. The ligament is a living tissue that allows teeth to move to keep contact with adjacent and opposing teeth as natural wear occurs. When a space is created by a missing tooth, this natural movement accelerates and the teeth may shift beyond normal ranges.
As a result you can encounter excessive mobility of teeth from bite irregularities, uneven tooth wear, bone loss, potential painful problems with the temporo-mandibular joints (connecting the lower jaw to the skull), and a loss in facial height.
There are three basic options for this kind of tooth replacement. The best option is dental implants: these free-standing replacements don't normally affect surrounding teeth, they're easier to clean, and they help support the bite. On the downside, there must be enough remaining bone to support the implant.
The next best option is a fixed bridge. This option only works, however, if there are teeth on either side of the missing tooth space capable of supporting the bridge, and they must be reduced in size by removing the enamel with the dental drill. They also have a tendency to retain plaque, the main cause of gum disease.
That leaves the last, and least favorable, option, a removable partial denture. They may also trap food and be difficult to wear. They can move in the mouth, stressing — and possibly loosening — the remaining teeth that hold them in place. With all its drawbacks, though, if a partial denture is the only solution to missing back teeth, it's a better alternative than doing nothing and risking long-term problems.

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.
