Although teething is a natural part of your baby's dental development, it can be quite uncomfortable for them—and upsetting to you. During teething, children can experience symptoms like pain, drooling or irritability.
Teething is the two or three-year process of intermittent episodes of the primary ("baby") teeth moving through the gums. These episodes are like storms that build up and then subside after a few days. Your aim as a parent is to help your baby get through the "stormiest" times with as little discomfort as possible. To that end you may have considered using over-the-counter products that temporarily numb irritated gums.
Some of those numbing products, however, contain a pain reliever called benzocaine. In recent years, this and similar ingredients have been found to increase the level of a protein called methemoglobin in the bloodstream. Too much methemoglobin can result in less oxygen delivered to body tissues, a condition known as methemoglobinemia.
This oxygen decrease can cause shortness of breath, fatigue or dizziness. In its severest form it could lead to seizures, coma or even death. Children and infants are at high risk for benzocaine-induced methemoglobinemia, which is why the U.S. Food and Drug Administration has banned marketing for benzocaine products as pain relievers for teething infants and children.
Fortunately, there are alternatives for helping your child weather teething episodes. A clean, chilled (not frozen) teething ring or pacifier, or a cold, wet washcloth can help numb gum pain. You can also massage their gums with a clean finger to help counteract the pressure exerted by an emerging tooth. Be sure, though, that you're not allowing anything in your child's mouth like lead-based paint that could be toxic. And under no circumstances should you use substances containing alcohol.
For severe pain, consult your physician about using a pain reliever like acetaminophen or ibuprofen, and the proper dosage for your child. With these tips you can help your child safely pass through a teething episode.
On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.
