Gum Disease (from bacteria)

 Mouth Bacteria (plaque)

Fluoride and Potassium Nitrate (medications used to treat tooth sensitivity):

Fluoride, a safe naturally-occurring element which dissolves in water, helps to lessen sensitivity in most teeth and to remineralize deminerilized areas on teeth if delivered as a bioavailable toothpaste, especially in children's teeth and elderly (usually bedridden) adults who do not remove plaque bacteria well. Potassium nitrate also causes less sensitivity by plugging up the nerve holes in tooth roots which cause sensitivity. Fluoride comes in many forms, and a popular useful style today is fluoride varnish, which can be applied in our dental office. Desensitizing toothpastes, also can help densensitize a little, because they contain low abrasivity, fluoride and potassium nitrate, which helps to protect the dental nerves.  We have powerful prescription fluoride supplements which can lessen sensitivity and lessen cavities, especially for those persons who are taking saliva-reducing medications (for heart disease, neurologic issues, etc) since calcium in the diet reach the mouth in saliva (when a person takes Calcium supplements for example).  If a person has xerostomia (low saliva flow) almost no calcium reaches the teeth from food eaten or calcium supplements.  

This is a cavity which became infected 

(a "dental abscess")>

 Dental Cavities:

Dental Cavities have been bothering humans for thousands of years.  A dental cavity is the name for the hole caused by the loss of mineral content which leaves teeth weakened and unhealthy due to bacterial contamination.  After the bacteria paste (called PLAQUE) sticks to teeth for just over a day, acid begins to form beneath the plaque and weakens the tooth.  This can happens with or without sugar--sugar just speeds up the process.  If allowed to continue, the cavities get bigger and bigger until they eventually become large holes.  A cavity will not go away by itself.  One way to repair a cavity is to fill in the hole, but this only works when there is still enough tooth left to fill.  If a cavity is large, it often requires a crown to strengthen the tooth for chewing.  If a cavity is deep, a tooth nerve can become infected, and the tooth will then often have severe pain.  Then, a root canal may save the tooth.  Only a well-trained and experienced dentist is capable of providing excellent root canal treatment.  Dentists know when a cavity is present, by doing a clinical examination and an x-ray examination, so the appropriate restorative treatment can then be given to infected teeth. 

Gum Disease & Gum Recession:

Gums protect the ​teeth.  For teeth to remain for a long time, the gums musts stay healthy. If bacteria are allowed to grow on a tooth, the gums can become infected, and this can cause the gums to fall away from the normal place on the root, which cause root recession. Besides not looking good and often becoming sensitive, gum recession reduces the amount of bone which attaches to a tooth, making it less stable, and also exposes the root of the tooth to sensitivity...a common occurrence.

Tooth Sensitivity:

When the root of a tooth is exposed, the nerves in the tooth root are also exposed, which can cause sensitivity to cold, acid, heat, and any other chemical irritants.  For example, coffee and ice cream for desert is a common sensitivity producer for recessed gums.

Odor Causing Infection


<​This is how I fixed the infection. First I removed the cavity, then disinfected the bacteria using ultrasonics and chemistry, then I filled the root with a long lasting material.. The tooth is thus saved and can be restored.

Most Halitosis (bad breath) is caused by bacterial fermentation, spicy food, or low saliva flow.  What can you do about bad breath fast?   Rather than use mouth perfumes, we have the answers.

We go to the source of Bad Breath and  chemically fix it by using science.  Ask us and we'll tell you how.
