For a child born with a cleft, a decayed baby tooth beside the cleft is more than a filling problem. Those teeth help hold space and guide the adult teeth during the bone graft and orthodontic stages that come later, so losing them early can make the bigger plan harder. Studies of children with clefts have generally found more decay and more enamel defects than in children without a cleft, which is why prevention sits so high on the cleft team's list.
What makes the teeth near a cleft more vulnerable
The upper front teeth develop in the same area as the cleft, so their formation can be disturbed. Enamel may be thinner, chalky or discoloured, and thinner enamel gives way to acid more easily. Teeth beside the cleft are often rotated, crowded or sitting at an angle, which leaves more corners for plaque to collect. Scar tissue from lip repair can make the upper lip tighter, and it can be harder to lift it out of the way to brush.
Other common differences include a missing upper lateral incisor on the cleft side, extra teeth near the cleft, and small or unusually shaped teeth. None of these is anyone's fault. They come from the way the teeth and the cleft form together, and the team plans around them.
Building a prevention routine from the first tooth
Begin cleaning as soon as the first tooth shows, with a soft, small brush. Australian guidance (ADA, teeth.org.au) is no toothpaste before 18 months unless a dentist advises it, a smear of low-fluoride children's toothpaste from 18 months to 6 years, and a pea-sized amount of standard fluoride toothpaste from 6, but because decay risk is higher near a cleft, your dentist or OHT may advise starting earlier. Brush twice a day, lifting the lip so you can see the teeth near the cleft clearly. Some parents find it easier to stand or sit behind their child with the child's head resting against them.
How often sugar is eaten matters, as well as how much. Keep sweet foods and drinks to mealtimes, offer water between meals, and avoid putting a child to bed with a bottle of milk, formula or juice. If your child is prone to decay or has weaker enamel, your dentist or OHT may suggest extra fluoride, such as a varnish applied at visits, or more frequent reviews.
Gum health matters too. Plaque left along the gumline causes red, puffy gums that bleed on brushing. Our article on gingivitis in children explains what to look for.
When decay or other problems do need treatment
If a baby tooth does develop decay, it can often be treated with a filling, or on a back tooth with a small preformed crown. Our article on kids crowns describes one way this is done without drilling.
Many children with a cleft palate have a narrow upper jaw, and an expansion appliance may be used to widen it, often before the bone graft. How a palatal expander works is covered in its own guide. Straightening the teeth later, usually with braces in the teenage years, is a planned part of correcting crooked teeth within the cleft plan.
When a young child needs a lot of treatment at once, it is sometimes done under a general anaesthetic in hospital. Lumi Dental does not provide general anaesthetic and refers where it is needed. For other situations, you can ask us about sedation options.
The cleft team and your local dentist
In Australia, cleft care is coordinated by multidisciplinary teams that can include surgeons, specialist orthodontists, paediatric dentists, speech pathologists and others. Oral health advice usually starts in the first months of life, and the team keeps track of the overall plan so families do not have to.
A local dentist or OHT can work alongside the team, seeing your child for regular check-ups, cleaning advice, fluoride and early treatment of decay between hospital visits. At Lumi Dental, our oral health therapists see children and families with a focus on prevention and gum health, and eligible children can be bulk billed under the Child Dental Benefits Schedule.
Much cleft care is delivered through public hospitals. For private dental care, fees depend on what is needed; see our deals and pricing page or ask for a written treatment plan with fees at a general check-up.
Common questions
How early should my baby see a dentist?
Within the first year, or when the first teeth appear. Early visits are mostly about advice and getting used to the chair.
My child's front teeth look patchy. Is that decay?
It may be an enamel defect, which is common near a cleft, or it may be early decay. A dentist or OHT can tell the difference and suggest protection such as fluoride varnish.
Will a missing tooth always be replaced?
Not always. Depending on the bite, the gap may be closed with orthodontics, or kept open and filled later with a bridge or an implant once growth is complete.
Booking a visit
If your child has a cleft lip or palate, regular dental reviews from infancy sit comfortably alongside the cleft team's care. Our team in Melrose Park is happy to see children with a cleft and their families for prevention and treatment. Get in touch through our contact page.
