Why Are My Teeth Wearing Away?

Rather than the abrupt changes that can occur from an accidental injury to the teeth, the subtle changes that can also occur from various forms of wear and tear can sneak up and cause considerable damage before you or your dentist sounds the alert that something is in fact damaging your teeth.  Loss of tooth structure can be caused by: Abrasion, Erosion, Attrition, Abfraction or a combination of these.ScrubberCleft in Gum

Abrasion is the loss of tooth structure from mechanical wear due to very abrasive toothpastes or aggressive scrubbing with a toothbrush.  Brushing damage shows up as recession and clefting of the gingiva around the necks of the teeth and the teeth appear to be worn smooth.  A high fiber diet can contribute to the problem and even more so the wearing of ball bearing jewelry in the mouth.  Significant damage to the edges of the front teeth can be caused by nail biting or using the teeth as a tool to strip wire.

Erosion is the loss of tooth structure due to acidic ph below 5.5.  Every time we eat or drink any carbohydrate (starch or sugar) our mouth takes a plunge into the acid abyss.  Fortunately saliva comes to the rescue and buffers the acid back above a 5.5 ph after one half hour.  In the absence of saliva for people with “dry mouths” decay Acidcan run rampant.  Acidity in the mouth can be worsened by frequent consumption of food or beverage or treats; this can be made even worse for patients with Gerd or stomach reflux.  Erosion of the enamel results in a thinning of the front teeth and potholes in the back teeth.  Fillings appear to be high or rough in teeth subject to acid erosion.

Attrition is the loss of tooth structure where the teeth touch each other from normal or abnormal function.  Bruxism can result in the most significant attrition since it usually occurs while we are sleeping; the uncontrolled pressure on the teeth can be nine times stronger than what we usually Bruxismapply while we’re awake.  Bruxism is commonly associated with the occurrence of obstructive sleep apnea in adults and children.  Bruxism is also the leading cause of migraine headaches which develop in the morning.  Bruxism can lead to individual tooth mobility and/or pain as well as TMD syndrome effecting the masticatory muscles and jaw joints (TMJ).  Non painful signs of Attrition include the shortening of the front teeth to the point where yellowish/brown dentin undeAbfraction-6r the worn enamel can be seen and all the teeth become flat after losing their anatomic curves and inclines.

Abfraction is the loss of tooth structure caused by excessive pressure on the teeth that results in tooth loss or damage not in an area where teeth actually function or rub against each other.  Bruxism or hyper functioning of the teeth can result in loss ofAmalgamFx-2 tooth structure on the sides of the teeth near the gum tissue where the zone of tooth flexure or bending occurs.  The other type of damage that can occur is the formation of a craze line that progresses to a crack and ultimately can result in the tooth fracturing.  The most common cause of tooth fracture is an old amalgam that is leaking and developing recurrent decay in the tooth which will swell like a cork in a bottle and eventually split the tooth.

So what can be done?

Many of the answers to your questions already exist in archived articles in this blog which you are welcome to explore. The most important step for you to take is to have a complete evaluation/exam by a dentist thoroughly knowledgeable on these subjects.  There are many simple preventive steps that can be taken and if the need arises, the miracles of modern dentistry will help you find a solution.

Migraine Headaches and TMJ Pain Relief With the NTI-tss

nti03nti02The NTI-tss stands for the Nociceptive(perception of things that could be harmful) Trigeminal(the fifth cranial nerve that branches to the eye, upper jaw and lower jaw) Inhibition; t(tension) s(suppression) s(system).  The NTI-tss is a small, virtually invisible mouthpiece that covers only your upper or lower incisor teeth while you sleep.  The NTI-tss is custom fitted by your dentist in about a 30 minute visit.

The NTI-tss is the only dental appliance approved by the FDA for the relief of migraine headaches.  It has a 70% success rate. It also has been used by myself and other dentists to successfully treat TMJ problems.

The key to the NTI-tss is the anterior bite plane (DE=Discluding Element) which sends feedback to your brain even while your asleep that reduces the level of masticatory muscle tension.

It is truly amazing to have a patient come in for a post insertion visit and remark that they had no idea how tense their oral muscles were until they used the apppliance and their muscles finally started to relax.

For a more detailed explanation of the NTI-tss, go to my web site www.drschwan.com or www.headacheprevention.com.  So how do you spell relief?  NTI-tss.
