Tooth sensitivity can be disheartening: you’re always on your guard with what you eat or drink, and perhaps you’ve even given up on favorite foods or beverages.
The most common cause for this painful sensitivity is dentin exposure caused by receding gums. Dentin contains tiny open structures called tubules that transmit changes in temperature or pressure to the nerves in the pulp, which in turn signal pain to the brain. The enamel that covers the dentin, along with the gum tissues, creates a barrier between the environment and dentin to prevent it from becoming over-stimulated.
Due to such causes as aggressive over-brushing or periodontal (gum) disease, the gum tissues can recede from the teeth. This exposes portions of the dentin not covered by enamel to the effects of hot or cold. The result is an over-stimulation of the dentin when encountering normal environmental conditions.
So, what can be done to relieve painful tooth sensitivity? Here are 3 ways to stop or minimize the symptoms.
Change your brushing habits. As mentioned, brushing too hard and/or too often can contribute to gum recession. The whole purpose of brushing (and flossing) is to remove bacterial plaque that’s built up on tooth surfaces; a gentle action with a soft brush is sufficient. Anything more than two brushings a day is usually too much — you should also avoid brushing just after consuming acidic foods or liquids to give saliva time to neutralize acid and restore minerals to the enamel.
Include fluoride in your dental care. Fluoride has been proven to strengthen enamel. Be sure, then, to use toothpastes and other hygiene products that contain fluoride. With severe sensitivity you may also benefit from a fluoride varnish applied by a dentist to your teeth that not only strengthens enamel but also provides a barrier to exposed dentin.
Seek treatment for dental disease. Tooth sensitivity is often linked to tooth decay or periodontal (gum) disease. Treating dental disease may include plaque removal, gum surgery to restore receded gums, a filling to remove decay or root canal therapy when the decay gets to the tooth pulp. These treatments could all have an effect on reducing or ending your tooth sensitivity.

The final emergence of permanent teeth in late adolescence marks the end of a long process beginning in the womb with the formation of our primary or “baby” teeth. Permanent teeth form in a similar way as buds high in the jaw, continuing to grow until the primary teeth ahead of them fall away. The crowns of the new adult teeth eventually break through the gum tissue and emerge (erupt) into view.
At least, that’s normally what should happen; sometimes, though, a tooth may only erupt partially or not at all, a condition known as impaction. The crown remains partially or fully submerged below the gum line, causing the tooth to press against other teeth, potentially damaging them. It can also make periodontal (gum) tissues adjacent to the area more susceptible to disease. Wisdom teeth are especially prone to this kind of impaction, to the extent they’re often surgically removed (extracted) to avoid future problems to adjacent teeth or the bite.
Upper canines (the “eye teeth” normally located directly below the eyes) are also subject to impaction. But because of their highly visible position, extracting them could have an adverse impact on the patient’s smile. In this case, we often attempt instead to expose and ultimately save the tooth.
Before taking any action, however, an orthodontic examination is conducted first to pinpoint the exact position of the impacted tooth and determine how that position might affect moving teeth into a more desired alignment. If we find the impacted canine is in a workable position, the next step is to surgically uncover the tooth from the gum tissue (a minor procedure usually performed by an oral surgeon or periodontist). Once exposed, an orthodontic bracket with a small attached gold chain is bonded to the tooth. The gums are then sutured back into place with the chain exposed and allowed to heal.
At some future point an orthodontist will attach the chain to orthodontic hardware that will pull the impacted tooth into proper position over several months. As a result, the upper canine becomes “un-impacted”; the dangers to surrounding teeth and tissues are also reduced. And, just as important, we can preserve the tooth and with orthodontics achieve an attractive, normal smile.

Ah, the baby teeth: those cute little pearl buttons that start to appear in a child’s mouth at around 6 to 9 months of age. Like pacifiers and bedtime stories, they’ll be gone before you know it — the last usually disappear by age 10-13. So if the dentist tells you that your young child needs a root canal, you might wonder why — isn’t that tooth going to be lost anyway?
The answer is yes, it is — but while it’s here, it has some important roles to play in your child’s development. For one thing, baby teeth perform the same functions in kids as they do in adults: Namely, they enable us to chew, bite, and speak properly. The primary teeth also have a valuable social purpose: they allow us to smile properly. If a baby tooth is lost prematurely at age 6, the child may suffer detrimental effects for five years or more — and that’s a long time for someone so young!
Even more important, baby teeth have a critical function in the developing mouth and jaw: Each one holds a space open for the permanent tooth that will eventually replace it — and it doesn’t “let go” until the new tooth is ready to come in. If a primary (baby) tooth is lost too soon, other teeth adjacent to the opening may drift into the empty space. This often means that the permanent teeth may erupt (emerge above the gum line) in the wrong place — or sometimes, not at all.
The condition that occurs when teeth aren’t in their proper positions is called malocclusion (“mal” – bad; “occlusion” – bite). It can cause problems with eating and speaking, and often results in a less-than-perfect-looking smile. It’s the primary reason why kids get orthodontic treatment — which can be expensive and time-consuming. So it makes sense to try and save baby teeth whenever possible.
Procedures like a root canal — or the similar but less-invasive pulpotomy — are often effective at preserving a baby tooth that would otherwise be lost. But if it isn’t possible to save the tooth, an appliance called a space maintainer may help. This is a small metal appliance that is attached to one tooth; its purpose is to keep a space open where the permanent tooth can come in.
If your child is facing the premature loss of a primary tooth, we will be sure to discuss all the options with you. It may turn out that preserving the tooth is the most cost-effective alternative in the long run.
