Dental Problems in Children: How to Detect Them in Time

Maintaining good oral health is important from the moment the first teeth appear. Dental problems in children usually develop silently: without pain or obvious symptoms in the initial phases, they can go unnoticed until they are advanced. Therefore, early detection, combined with periodic check-ups at a dental clinic specialized in children, is the most effective tool to protect children’s oral health.

At Asensio Dental Clinic, we recommend the first visit upon turning one year old, and check-ups every six months thereafter. At each visit, we perform a complete clinical examination that includes digital orthopantomography and a 3D scanner, allowing us to detect problems that are not visible to the naked eye.

Warning signs that parents should know

Stains or changes in tooth color. Opaque white spots are the first sign of enamel demineralization—incipient cavities—and can be reversed if acted upon in time. Yellow, brown, or black spots indicate that the cavity has already advanced. Any color change that does not disappear with brushing deserves an evaluation.

Sensitivity or pain when eating. If the child rejects cold, hot, or sweet foods, or complains of pain when chewing, it may be a sign of active cavities that have reached the dentin or even the nerve. In younger children, who cannot express pain clearly, it may manifest as irritability, refusal to eat, or disturbed sleep.

Inflammation of the gums or abscesses. Reddened, swollen gums or gums that bleed during brushing are not normal in children with proper hygiene. A lump or pimple on the gum near a tooth may indicate a dental abscess that requires urgent attention.

Persistent bad breath. Bad breath that does not improve with brushing may be a sign of active cavities, incipient periodontal disease, or dental infection.

Teeth that do not come in or erupt late. The eruption of permanent teeth follows an approximate order and schedule. If a permanent tooth has not erupted when it should, or if there is asymmetry between the two sides, it should be evaluated with an X-ray.

Oral habits that deform the bite. Prolonged use of a pacifier beyond age 3, thumb sucking, or habitual mouth breathing can alter jaw development and generate malocclusions. The sooner they are detected and addressed, the simpler the correction.

Most frequent dental problems in children

Early childhood cavities. These especially affect the upper incisors and are associated with nighttime bottle use. It is the most aggressive form of childhood cavities and can destroy teeth in a short time. You can read more about their causes and treatment in our article on childhood cavities.

Malocclusions. Crossbite, open bite, or dental crowding are developmental alterations that in many cases can be corrected more easily if detected before age 7-8, when jaw growth is still moldable. Childhood orthodontic treatment in this phase is called interceptive orthodontics.

Dental trauma. Falls and bumps are very frequent in childhood. Trauma can fracture the tooth, displace it, or even knock it out. In all these cases, you must go to the dental clinic as soon as possible: an avulsed permanent tooth has a chance of being replanted if acted upon within the first 60 minutes.

Enamel defects. Some children have hypoplastic enamel—areas of incomplete or porous enamel—which increases the risk of cavities and dental sensitivity. These defects can be detected during the check-up and protected with sealants and fluoride applications.

When to take the child to the dentist without waiting for a check-up

There are situations that should not wait for the next scheduled check-up and require an urgent visit: dental pain that does not yield to usual analgesics, trauma affecting a permanent tooth, abscess or facial inflammation, avulsed (knocked out) permanent tooth, or any sudden change in the child’s behavior that may be related to oral pain.

For other situations—stains, mild sensitivity, changes in the bite—an ordinary consultation within a few days is sufficient. The important thing is not to ignore the signs and not to wait for the child to complain of intense pain, which usually indicates that the problem is already advanced.
