Top Dental Symptoms: Sensitive Teeth

If your teeth hurt when you drink hot or cold beverages, you may have sensitive teeth. This can be the result of tooth decay, fractured teeth, worn fillings, gum disease, worn tooth enamel or an exposed tooth root due to gum recession. Treatment will depend on the source of sensitivity. If youíre concerned about the sensitivity of your teeth see your dentist for diagnosis and treatment options.

Top Dental Symptoms: Mouth Sores

Types of mouth sores include canker sores, cold sores, leukoplakia and candidiasis. They vary in their severity and causes. Mouth sores could be the symptom of a disease or disorder; infection from bacteria, viruses or fungus or result from irritation caused by braces, dentures or the sharp edge of a broken tooth or filling. Your dentist should examine any mouth sore that lasts a week or longer.

Dental Recession - Receding Gums & Root Exposure


Recession (“Gums receding” & Root exposure)
I still hear people telling me that they used to “brush too hard” and that’s the reason they have receding gums.  For the most part, the basis for this comes from a series of articles written in the 1950’s that in fact did not present any research to support these statements.  Since the late 1960’s manufacturers have used polished tipped nylon bristles and in fact have determined that these are safe and cause no appreciable wear to tooth surfaces even at levels that people would never reach in their lifetimes.  Tooth pastes (dentifrices) have also been formulated to prevent wear to tooth surfaces.  More recent research techniques have described, in detail, the bio-mechanical reasons for the development of recession.

So what causes it? 

First, when teeth come into the mouth in a crooked position the gum tissues may not come to the level that they should, and prominent root surfaces may not be covered by the bone of the jaw.  Also because of this poor eruption pattern the type of tissue (gingiva) may also not cover and surround the tooth as desired.
These several reasons are the most common to explain recession on front teeth.
                         

Second, natural variations in the position of muscle attachments going to the lips may cause undo pressure on the gum tissues (gingivae) pulling the gums away from the tooth root. 




 
Third, the most common reason overall is due to unnatural angles of forces acting on the teeth.


Teeth are supported in their bony socket by a series of connective tissue ligaments . These ligaments act as a “shock absorber” for the millions of times you load the teeth in normal function (eating,etc.) in your life.  A millimeter or two of the gums shrinking over decades of use is not unexpected and usually is painless and has little health consequences, except that sometimes the spaces between the teeth get a little bit bigger.

However, the problem is when the tooth is subjected to a lot of forces that are coming from angles or from the side, such as in cases where people grind their teeth, clench their teeth, or, even more commonly, have crooked or angled teeth so they chew on the “sides” of their teeth.

Modern research techniques in stress analysis have demonstrated that teeth will, in fact, bend under angular loads of force.  This prevents the teeth from breaking, but will result in a breakdown of the tooth material at the point where the tooth bends.  The common groove that people will notice on some teeth at or near the gumline are result of this tooth breakdown.  These grooves can get pretty substantial and may require a “filling” to fill in the space and an “adjustment”, or recontouring of the top of the tooth, to try and redirect the forces.   See image to the right >>

Fourth, accidental trauma from food or poor cleaning techniques can also cut the gingivae.  People wearing removable partial dentures can also cause recession to some of the supporting teeth.  Though this is a combined issue of trauma and increased function from the load of the clasps of the denture.

Fifth and an important consideration.  If a person has gum disease, the resultant bone and tissue loss is also considered recession.  However, this recession is considered pathological and bacterial based.  The treatment can be very different than what we are discussing in this article.  The focus of this article is recession (though considered pathological) that is mechanical in origin, which is the most common.

Why can it hurt and be sensitive to cold?

If you look at the tooth root under a microscope, it is not solid.  In fact, it looks like Swiss cheese!  You may have seen this in advertisements on TV or magazines for sensitive teeth toothpastes.  These holes are connected to the “nerve” (soft tissue inside the tooth)of the tooth, so the tooth will respond to cold and some types of spices with an uncomfortable response.  With time these holes become “plugged up” and the direct connection ceases, but those teeth with active recession will continue to lose the outermost layers of the tooth and the holes on the root surface continue to reopen.              

What is the treatment?

There are different levels of treatment. 

The first is to “plug the holes”.
 That is how the “sensitive toothpastes” work, and why you need to continue using them.  Flouride treatments can also help, working in a similar manner.

The second is to cover it. 
Fillings into the recession area to “cover the holes” are commonly used.  Gum surgery techniques are also used to cover the area and also address the esthetic issues that recession can cause.



The third is to change it. 
If the most common source of recession is the unnatural, angled forces applied to the teeth, then attempts to change these forces to become more “vertical” are indicated.  The most common of  these are the “adjustments” to recontour the teeth as previously mentioned.  The second is to restore some of the teeth (canines or “eye”teeth) which can wear down over time and no longer provide a guiding , protective function.  The third and often best technique is orthodontic.  Teeth which are angled or crooked can be realigned in a more vertical manner so the forces of chewing become more vertical as well.  Most of the time, sensitivity will completely disappear, and we have seen cases where the gum tissues will start to “come back”, though rarely to perfect levels. A combination of all of these usually give the best results.

 
What happens if I do nothing?

It is rare that someone will lose a tooth primarily because of recession.  It’s not going to just fall out one day. 

The teeth will continue to remain sensitive and be uncomfortable.
As the tooth loss on the root continues the “nerve “ of the tooth can die.  Though the tooth will no longer bother you, endodontic (root canal) treatment may be indicated.

As the tooth loss continues and the root becomes weaker, the remaining tooth can fracture off.

If you do develop any periodontal (gum) problems in the future, the angular forces will contribute to the speed at which the disease will progress, and could interfere with  treatment and your ability to heal.

Many will find the “long in the tooth” look to be unappealing. 

You may become more susceptible to decay of root surfaces, which in fact is different from the common decay of children and adults.  With many of the medications that we are taking as we age , reduced salivary flow is a side effect, and the increase in root decay as a result of that reduced salivary flow, is an alarming trend.

Top Dental Symptoms: Toothache

If your mouth or jaw hurt, it could be from a toothache. Toothaches usually indicate a cavity but they can also signal gum disease. In some cases, a toothache is a sign of an abscess or impacted tooth. A toothache should be evaluated by a dentist right away to determine the cause of the problem and prevent the tooth from dying.
