Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

Along with daily brushing and flossing, limiting your child’s sugar consumption is an important way to prevent tooth decay. We all know the usual suspects: candy, sugar-added snacks and sodas. But there’s one category you may not at first think fits the profile—juices. But even natural juices with no added sugar can raise your child’s risk of tooth decay if they’re drinking too much.
Tooth decay is caused by certain strains of bacteria in the mouth, which produce acid. Sugar in any form (sucrose, fructose, maltose, etc.) is a primary food source for these bacteria. When there’s a ready food source, bacteria consume it and produce abnormally high levels of acid. This can cause the mineral content of tooth enamel to dissolve faster than saliva, which neutralizes acid, can reverse the tide.
Juices without added sugar still contain the natural sugar of the fruit from which they originate. The American Academy of Pediatrics conducted a study of the effect of these natural juice sugars on dental health. Their conclusion: it can have an effect, so the amount of juice consumed daily by a child should be restricted according to age.
They’ve since published guidelines to that effect:
- Under age 1 (or any child with abnormal weight gain): no juice at all;
- Ages 1-3: no more than 4 ounces a day;
- Ages 4-6: no more than 6 ounces a day;
- Ages 7-18: no more than 8 ounces (1 cup) a day.
Again, these are guidelines—you should also discuss the right limits for your individual child with your dentist or pediatrician. And if you’re wondering what kind of beverages pose less risk of tooth decay, you can look to low or non-fat milk. And, of course, don’t forget water—besides containing no sugar, nature’s hydrator has a neutral pH, so it won’t increase acidity in the mouth.
Tooth decay is one of the biggest health problems many kids face. But with good teeth-friendly habits, including restricting sugar intake in any of its many forms (including juices) you can go a long way in reducing their risk of this destructive disease.
