What kind of doctor treats Cleft Tongue?
A primary care doctor or dentist is a good first stop for any tongue concern. If the split needs special care, they may refer you to an oral surgeon, an ear, nose, and throat doctor, or a genetics doctor. Many people with a mild split need nothing more than advice on keeping the tongue clean.
What it is
A cleft tongue, also called a bifid tongue, is a split in the tongue, most often at the tip. People are born with it. It is rare. It is different from a fissured or furrowed tongue, which is a more common condition with many small grooves on the surface of the tongue. A cleft tongue can happen by itself, or it can be one sign of a larger inherited condition.
Symptoms
The main sign is a tongue that looks split or has two tips. Some people have no other problems. Others may have trouble with speech, eating, or keeping the tongue clean. Food can get stuck in the split and cause irritation. If the cleft is part of a larger condition, there may be other signs in the mouth, face, or fingers and toes.
Causes and who gets it
A cleft tongue forms before birth, when the two sides of the tongue do not join fully as the baby grows. Doctors do not always know why this happens. It can be one sign of a group of rare inherited conditions called oral-facial-digital syndromes. These conditions affect the mouth, the face, and the fingers and toes. In the most common type, a split in the tongue can occur along with a cleft palate, which is a gap in the roof of the mouth. That type is caused by changes in a gene called OFD1.
How doctors diagnose it
A doctor or dentist can usually spot a cleft tongue just by looking at it. If the split might be part of a larger condition, the doctor will check the mouth, face, hands, and feet. They may also ask about family history. A genetics doctor can offer gene testing when it is needed.
Treatment
Treatment depends on how much the split affects the person. Many people need no treatment. Brushing the tongue gently and rinsing after meals can help keep the split clean. If the split causes trouble with speech or eating, a specialist can talk about options, which may include speech therapy or surgery to repair the tongue. If it is part of a larger condition, a team of doctors usually plans the care.
When to see a doctor
See a doctor or dentist if a baby is born with a split tongue, so the mouth, face, and hands can be checked. Also see a doctor if the tongue becomes painful, swollen, or infected, or if there is trouble feeding, speaking, or swallowing. Sores that do not heal are another reason to make an appointment.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid with a flat monthly fee instead of insurance for visits. A concierge doctor works similarly but usually charges more and often works alongside your insurance. Either type can examine your tongue and advise on daily cleaning. If the split needs surgery or looks like part of a larger condition, they would refer you to the right specialist.
Common questions
Is a cleft tongue dangerous?
By itself, it is usually not dangerous. The main concerns are speech, eating, and keeping the split clean. If it is part of a larger condition, other health problems may need care.
Is a cleft tongue the same as a fissured tongue?
No. A cleft tongue is a rare split in the tongue, often at the tip. A fissured tongue is a common condition with many small grooves on the top of the tongue. They are different conditions.
Can a cleft tongue be fixed?
Many people do not need any repair. When the split causes problems with speech or eating, surgery can be considered. A surgeon can explain what is likely to help in each case.
Does a cleft tongue mean my child has a syndrome?
Not always. It can happen on its own. Because it can also be one sign of a larger inherited condition, a doctor will usually look for other signs in the mouth, face, hands, and feet.
