Parents will do just about anything to relieve their children's discomfort when they're in pain. When a toddler is suffering through a teething episode, it's tempting to turn to a topical numbing ointment to soothe their gums.
But there can be a hidden danger for kids if you use certain over-the-counter products used by adults for gum or teeth pain. Many of these topical ointments contain a pain reliever called benzocaine. While it's relatively safe for adults, benzocaine can be hazardous for infants and young children.
Studies have found that benzocaine contributes to a disease called methemoglobinemia, in which a protein in the blood called methemoglobin increases to abnormal levels. Too much of this protein inhibits the transport of oxygen throughout the body. For young children, this can cause shortness of breath, fatigue and dizziness. In extreme cases, it could lead to seizures, coma or even death.
Parents are urged to avoid using any product containing benzocaine to ease gum or teething pain in children. Instead, the American Academy of Pediatric Dentistry recommends providing a child a chilled (not frozen) teething ring, pacifier or a damp clean cloth to chew on. The chewing action helps relieve gum swelling pressure and the cold will help numb the pain. Massaging the gums with a clean finger may also help.
If the pain persists, parents should consult a doctor or pharmacist about giving their child pain medication. Drugs like ibuprofen or acetaminophen (never aspirin) administered in the proper dosage for a child's age can help ease teething discomfort. Medications should always be given orally—you should never rub substances like aspirin or alcohol directly on the gums, which can further irritate already inflamed tissues.
Teething episodes come and go during a child's early dental development—they are like storms that swell and abate before they finally pass. Except when accompanied by fever or diarrhea, there's no need for concern. Your main goal is to help ease their discomfort as much—and as safely—as possible.
Besides straight and translucent teeth, an attractive smile has another important component: balance. In a great smile, the visible areas of the teeth and gums are in balanced proportion to one another.
But what is the ideal proportion between teeth and gums? Although aesthetic appeal is largely “in the eye of the beholder,” dental professionals typically consider a properly sized tooth to be around 10 mm in visible length. As for the upper gums, no more than 4 mm of tissue should show when smiling. Teeth appearing shorter than 10 mm or the gums displaying more than 4 mm can create an effect called a “gummy smile.”
Fortunately, there are different approaches for correcting a gummy smile, depending on what's causing the appearance of gumminess. Not only are there different causes, but they can be diverse in nature.
Obviously, an actual excess of gum tissue can cause a smile to look gummy—but so can shortened teeth. One possible solution called crown lengthening could help correct either possibility. During the procedure, we remove any excess gum tissue or reposition the gums after reshaping the underlying bone to reveal more of the tooth crown. Worn or shortened teeth can also be made to look longer with porcelain veneers.
A gummy smile could also be caused by a hypermobile lip, in which the lip rises higher than normal while smiling. We may be able to prevent this temporarily by injecting Botox into the lip muscles, which paralyzes them and inhibits their ability to move upward. A more permanent approach is to surgically restrict the upward movement of the lip muscles.
The gums may also seem too prominent if the upper jaw is longer in proportion to the face. One way to correct this is orthognathic surgery, a procedure that moves the upper jaw to a higher position on the skull. This can reduce the jaw profile with the face and subsequently affect how much of the gums show while smiling.
These solutions range from relatively minor to significantly invasive. The first step, though, is to find out what's really behind your gummy smile before taking the next step to make it more attractive.

Your child's dental development is in overdrive between birth and early adulthood. The rapid growth of the teeth, gums and jaws occurs mostly on its own—but tooth decay could significantly derail it.
Although most cases of dental disease occur in adults, tooth decay is a major problem for children, particularly involving primary teeth. These teeth are much more important than they seem given their short lifespans: Because they help incoming permanent teeth to align properly, their premature loss due to decay can create future bite problems.
To prevent this from happening, taking steps to prevent tooth decay in young children is well worth the effort. The best strategy is a double-pronged approach. You'll first want to address certain areas that directly contribute to tooth decay. You'll then want to add measures that strengthen the teeth themselves against the disease.
In regard to the former, reducing the levels of harmful bacteria in the mouth tops the list. These bacteria produce acid as a byproduct that in turn softens and erodes enamel, the teeth's natural barrier against decay. We reduce bacteria by eliminating dental plaque, a film of built-up food particles that feeds and shelters bacteria, through daily brushing and flossing.
Certain dietary choices may also contribute to bacterial growth. Refined sugar is a prime food source for bacteria, so limiting it in the diet will help reduce tooth decay. Furthermore, a diet rich in whole, unprocessed foods and dairy provide nutrients strengthen teeth against decay.
The other prong in defeating tooth decay mainly involves protective measures provided by your dentist. Sealants applied to the chewing surfaces of a child's teeth help protect the enamel from the buildup of bacteria in these highly susceptible areas. An occasional direct application of fluoride to teeth further strengthens their enamel, and makes them less susceptible to decay.
This approach can minimize the chances of tooth decay, but it won't eliminate the risk altogether. If it does occur despite your best efforts, prompt treatment can limit the damage and preserve the teeth. Working with your dentist, you can help ensure your child's teeth are protected from this damaging disease.
