Millions of people suffer from mouth dryness, but most people just never talk about it. As your dental care providers, we don't want you to keep it a secret anymore and mouth dryness really can be a problem.
Why? Saliva is a very important fluid that moisturizes, lubricates, and aids in the first stages of chewing and digestion. A normal flow of saliva provides antibacterial benefits that even protect against cavities by buffering the effects of acids. It can also make the surfaces of your teeth more vulnerable to abrasion and erosion. Without enough saliva, you may be especially at risk for not only tooth decay, but even yeast infections.
Causes of dryness include dehydration and even morning breath, both of which are normal. Smoking, alcohol and coffee drinking also cause dryness. It is also a side effect of many medications. Although mouth dryness is not a disease in itself, it could be a symptom of salivary gland or other systemic (general body) disease.
As a first step in the treatment, we will assess your situation by taking a detailed habit, diet, medical, and drug history to properly assess the cause and establish whether this is a local condition affecting only your mouth or an indication of a generalized bodily problem.
It's always helpful to keep yourself well hydrated by simply drinking a sufficient amount of water every day and by using good daily oral hygiene to remove dental bacterial plaque. Chewing gum, especially containing Xylitol, will also help promote saliva flow and keep your mouth moist. Be careful not to suck on candy or mints, because they are likely to cause decay. There are also prescription medications that can be used to promote more saliva flow.
While the goal of restorative dentistry is to return all of the destroyed or lost dental tissues of the teeth to full form (shape) and function, when you blend this goal with the artistry of cosmetic dentistry, the results can be dazzling. Today's modern techniques and materials enable replacement of missing tooth structure that allows bonding directly to the tooth so that it not only is an exact color match but also actually strengthens the tooth. And tooth-colored fillings are not just for front teeth. They can dramatically improve the appearance of all teeth — even your back molars — so that it appears you've never had tooth decay at all!
All of this is accomplished through the use of either tooth-colored dental porcelain or composite resins. Porcelains are a form of ceramic material formed by the action of heat. They are available in many colors and shades made from a powder corresponding to the primary color of the natural tooth structure that is mixed with water and placed into an oven for firing (hence their ceramic nature). When built up in layers by highly trained dental ceramicists, they can be made to mimic the exact natural translucency, staining and contours of tooth enamel.
Dental composite resins are the most common materials used for tooth-colored adhesive restorations today and have properties similar to tooth structure. They consist of resin or special plastics and fillers that are made of silica, a form of glass. The fillers give the composites wear resistance and translucency (see through properties).
It is important to note that besides providing the appearance of beautiful teeth, properly restored teeth function and wear better. But most important to you, they appear indistinguishable from natural teeth! Furthermore, scientific studies and clinical experience have validated their use as both safe and predictable. In fact, these techniques are also suitable for children's teeth and can incorporate fluoride to reduce decay. Together, all of these changes have so significantly impacted the way modern dentistry is practiced that many believe we may have entered into the so-called “post-amalgam (silver metal-colored dental fillings) era.”

Dental implants traditionally have a high success rate with numerous studies showing long-term success rates of over 95%. This is just one of the reasons they have been widely accepted as the best method for permanently replacing missing teeth. In fact, over-dentures, which are full dentures supported and stabilized by at least two dental implants, are now considered the standard of care by the American Dental Association (ADA) for people who have lost all of their teeth in one or both jaws. And while they have a high success rate, there are some factors that can compromise the success rates of implants.
These factors are generally divided into three categories: general health concerns, local factors, and maintenance issues.
- General health concerns: Your general health, lifestyle, and habits can play a major role in the success of dental implants. For example, smoking, diabetes, osteoporosis (porous bone) or a compromised immune (resistance) system can all negatively impact implant healing and success. And if you have a history of radiation treatment to your jawbones, you are at a higher risk for complications.
- Local factors: Some examples of local factors that can affect implant success include bone quality and quantity — having sufficient bone in the right place to accurately secure and locate the implants.
- Maintenance issues: While implants are excellent high tech replacements for missing permanent teeth, they do require routine maintenance. This includes daily cleaning and continued professional care. Otherwise, implants are just like any other technically sophisticated devices — they may be susceptible to breakdown.
A pregnant woman has a lot to think about while preparing to welcome a new member of her family. It's important to think about her oral health as well. She is sharing her body with the developing infant, so problems with her health — including her dental health — can affect the baby. The following facts will help you understand the relationship between oral health and pregnancy.
- A baby's primary (baby) teeth begin to form during the sixth week of pregnancy. They begin to form their enamel (the hard outer layer of the teeth) and dentin layer (just under the enamel) at about the third or fourth month. The calcium, phosphorous, and protein that are needed for these structures must all be provided by the mother's diet.
- A good diet for a pregnant mother, in order to provide for both her needs and those of the fetus (the developing baby), includes whole grains, fruits, vegetables — including green leafy vegetables — proteins and dairy products. A doctor may also recommend iron and/or folic acid supplements.
- If the mother's diet does not provide enough calcium for the baby's bones and teeth, it will come from calcium stored in her bones — not from her teeth. The old idea that a mother's teeth lose calcium during pregnancy has been found to be a myth.
- Progesterone, a normal female hormone, is elevated during pregnancy. This hormone stimulates production of prostaglandins, substances that cause inflammation in gum tissues if the bacteria that cause periodontal (gum) disease are present. The resulting swelling, redness, and sensitive gum tissues, called pregnancy gingivitis, are common during the second to eighth months of pregnancy.
- The bacteria involved in periodontal disease can affect whole body conditions such as heart disease and strokes, diabetes, and respiratory diseases. The inflammation resulting from such bacteria can also cause premature delivery (birth before 37 weeks of pregnancy) or low birth weight in the baby.
- Periodontal disease is also related to pre-eclampsia, or high blood pressure, during pregnancy.
- Dental x-rays do not expose the mother to very high radiation, but in any case every precaution is taken to minimize exposure to the fetus. These include a leaded apron that shields the baby from exposure.
- Most drugs commonly used in dentistry, including local anesthetics, can safely be given to pregnant women without affecting the fetus. However, it is important to let your dentist know you are pregnant before embarking on any treatment to make sure anything that is done will be safe for the fetus and its developing teeth.
