The American Academy of Pediatrics and other healthcare organizations recommend breastfeeding as the best means for infant feeding. While bottle feeding can supply the nutrition necessary for a baby's healthy development, breastfeeding also provides emotional benefits for both baby and mother.
But there might be an obstacle in a baby's mouth that prevents them from getting a good seal on the mother's breast nipple—a small band of tissue called a frenum. This term describes any tissue that connects a soft part of the mouth like the upper lip or tongue to a more rigid structure like the gums or the floor of the mouth, respectively.
Although a normal part of anatomy, frenums that are too short, thick or inelastic can restrict a baby's lip or tongue movement and prevent an adequate seal while nursing. The baby may adjust by chewing rather than sucking on the nipple. Besides a painful experience for the mother, the baby may still not receive an adequate flow of breast milk.
Bottle-feeding is an option since it may be easier for a baby with abnormal frenums to negotiate during nursing. But the problem might also be alleviated with a minor surgical procedure to snip the frenum tissue and allow more freedom of movement.
Often performed in the office, we would first numb the frenum and surrounding area with a topical anesthetic, sometimes accompanied by injection into the frenum if it's abnormally thick. After the numbing takes effect, we gently expose the tissue and cut it with either surgical scissors or a laser, the latter of which may involve less bleeding and discomfort. The baby should be able to nurse right away.
If you wait later to undergo the procedure, the baby may already have developed compensation habits while nursing. It may then be necessary for a lactation consultant to help you and your baby "re-learn" normal nursing behavior. It's much easier, therefore, to attempt this procedure earlier rather than later to avoid extensive re-training.
While there's little risk, frenum procedures are still minor surgery. You should, therefore, discuss your options completely with your dental provider. Treating an abnormal frenum, though, could be the best way to realize the full benefits of breastfeeding.
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.
