In short. From the first baby teeth to the final bite: what a cleft means for teeth and jaws, and how dental, orthodontic and surgical care fit together over the years.
Key points
- Orthodontics may prepare the dental arch before alveolar bone grafting, so that the grafted bone ends up in the right place.
- Grafting then gives the adult canine a route and a foundation.
- Orthodontics finishes the alignment afterwards.
A cleft that involves the gum affects the teeth, and the teeth in turn affect the shape of the face. Dental and orthodontic care is therefore not an optional extra in cleft treatment; it runs the whole length of the sequence, from the first tooth to the final bite.
The first teeth
Babies with a cleft may erupt their first teeth slightly earlier or later than other children, and a tooth next to the cleft may be missing, misshapen, or out of position. Clean teeth matter more than usual, because decay near a cleft repair can threaten the repair itself. Brushing from the very first tooth and early dental visits establish habits that pay off later.
Mixed dentition and the case for orthodontics
As the adult teeth begin to come through, problems usually become clearer. The cleft side of the arch may be narrow, the teeth may be rotated or crowded, and the upper and lower teeth may not meet properly. Orthodontics is used to expand and align the arch, to prepare space for the adult canine around the time of bone grafting, and to create a bite that works and looks balanced.
How it fits with surgery
Coordination, not sequence for its own sake
Orthodontics may prepare the dental arch before alveolar bone grafting, so that the grafted bone ends up in the right place. Grafting then gives the adult canine a route and a foundation. Orthodontics finishes the alignment afterwards. In some children the growth of the upper and lower jaws is uneven, and in a minority corrective jaw surgery as a young adult is the right way to finish the bite. Each step depends on the one before it.
Beyond alignment
Teeth that are missing, or that cannot be kept, are often replaced later once growth has finished, using a bridge or an implant placed in bone that has been grafted and prepared. Regular dental care continues lifelong. A person who had a cleft is no more finished with their teeth at eighteen than anyone else is.
Honest limits
Orthodontics takes years, requires regular appointments and diligent wear of whatever appliance is prescribed, and will not produce a perfect result in every mouth. Some teeth are missing and stay missing. Some bites can only be finished with jaw surgery, which carries its own risks and recovery. An aligned, healthy bite is one of the most durable things cleft care can give someone.
See a dentist promptly if
- There is toothache, swelling of the gum or face, or a broken or loose tooth near the cleft repair.
- A tooth erupts through an ungrafted gum gap, or the gum bleeds or swells around a tooth.
- An orthodontic appliance breaks, becomes loose, or causes ulceration in the mouth.
Frequently asked questions
Why does a cleft affect the teeth?
A cleft that involves the gum affects the ridge that holds the teeth. A tooth next to the cleft may be missing, misshapen or out of position, and as the adult teeth come through, the cleft side of the arch may be narrow, the teeth crowded, and the upper and lower teeth may not meet properly.
How does orthodontics fit with cleft surgery?
Orthodontics may prepare the dental arch before alveolar bone grafting, so the grafted bone ends up in the right place. Grafting then gives the adult canine a route and a foundation, and orthodontics finishes the alignment afterwards. In a minority, corrective jaw surgery as a young adult is the right way to finish the bite.
Is dental care for a cleft finished by eighteen?
No. Teeth that are missing, or that cannot be kept, are often replaced later once growth has finished, using a bridge or an implant placed in bone that has been grafted and prepared. Regular dental care continues lifelong, and orthodontics takes years and will not produce a perfect result in every mouth.
Risks & Limitations
- Cleft care spans years and usually several operations. A single procedure does not finish it, and the plan may change as a child grows.
- Scars from lip and nasal repair are permanent. They fade and soften, but they never disappear.
- Speech may still need therapy, or further surgery for velopharyngeal insufficiency, after palate repair.
- Hearing problems and repeated ear infections are common, and may need ventilation tubes and long-term ear review.
- Feeding difficulties before and after repair, including slow feeds and poor weight gain.
- Dental and orthodontic problems: missing, misplaced or crowded teeth, and a bite that needs years of treatment.
- Growth disturbance of the upper jaw, which may require later revision or corrective jaw surgery.
- No outcome is guaranteed. Perfection is not achievable and is not the goal.
When to Seek Care
- A baby who cannot feed, coughs or chokes during feeds, or is losing weight or not gaining it.
- Difficulty breathing, noisy breathing, or pauses in breathing, especially after palate repair.
- Fever with a repair site that is red, hot, swollen or discharging.
- Bleeding from a lip or palate repair that does not stop with gentle pressure.
- Fluid or discharge from the ear with pain or fever, or any suspected change in hearing.
