What Causes Cavities in Children?
A cavity is a hole in the tooth created when bacteria in plaque turn sugars and starches into acid, and that acid dissolves the mineral in enamel faster than saliva can replace it. It is a process, not an event. In children the process moves quickly, because baby tooth enamel is thinner and softer than adult enamel.
The pattern Dr. Abbas sees most often at our Brampton office is not candy. It is frequency. A juice cup carried around all afternoon, a bottle at bedtime, or constant grazing keeps the mouth acidic for hours. Ten minutes of dessert after dinner does less damage than a sippy cup that never leaves a toddler’s hand. Tooth decay is still the most common chronic disease of childhood in Canada, and almost all of it is preventable.
How Do I Know If My Child Has a Cavity?
Often you will not, and that is the point of 6-month visits. Early decay causes no pain at all. By the time a child complains, the lesion has usually reached the softer dentine underneath the enamel. Dr. Abbas finds most early cavities visually and with bitewing X-rays before a child feels anything.
Signs worth a call to our Brampton office include:
- A white, chalky, or brown spot on a tooth that does not brush away
- Complaints about cold, sweet, or sticky foods
- A visible hole, pit, or dark shadow
- Chewing only on one side, or avoiding a particular food
- Persistent bad breath, or a gum pimple near a back tooth, which can signal infection
- Night waking with tooth pain, which should be seen promptly
How Does Brampton Smiles Treat a Cavity in a Child?
Treatment is matched to depth. Dr. Abbas always chooses the most conservative option that will actually hold, because every restoration on a young tooth sets up what that tooth needs later.
- Fluoride therapy. A very early lesion that has not broken through the enamel surface can often be remineralized with professionally applied fluoride varnish plus changes at home. No drilling, no freezing.
- Tooth-coloured filling. The standard treatment once decay has broken the surface. The decay is removed and the tooth is rebuilt with composite that matches the tooth. We do not place new amalgam.
- Crown. When a baby molar has lost too much structure for a filling to hold, a prefabricated crown covers and protects the whole tooth until it exfoliates naturally.
- Pulp treatment. When decay has reached the nerve of a baby tooth, the affected pulp is treated and the tooth is sealed and crowned, which keeps it in place rather than extracting it early.
- Extraction. The last option, used only when a tooth cannot be saved. If a baby tooth comes out well ahead of schedule, we usually discuss a space maintainer at the same visit.
Parents sometimes ask why we bother fixing a tooth that is going to fall out anyway. The honest answer is that an untreated baby molar can abscess, and an abscess sits directly above the developing adult tooth. Losing that molar early also costs the space the permanent premolar needs. Neither is a trade worth making.
Will Cavity Treatment at Brampton Smiles Hurt My Child?
Most children are comfortable throughout. We use topical numbing gel before any freezing, warm the anesthetic, and go slowly. Dr. Abbas explains each instrument in child-friendly terms and lets the child touch it first. A raised hand stops everything immediately, and children take that agreement seriously once they learn it is real.
For anxious children, or for longer appointments, we book extra time rather than rushing, and oral sedation is available where appropriate. See sedation options. Parents are welcome in the room with younger children.
How Can My Child Avoid the Next Cavity?
Prevention at Brampton Smiles is built around three things that actually change outcomes: reducing how often sugar is in the mouth, brushing twice daily with fluoride toothpaste in an age-appropriate amount, and sealing the deep grooves of permanent molars as they erupt.
Sealants are the highest-value preventive step we offer for school-age children, because the chewing surfaces of the first permanent molars are where most childhood decay begins. We usually place them around age 6 and again around age 12.
Does CDCP or Insurance Cover Children’s Fillings at Brampton Smiles?
The Canada Dental Care Plan covers eligible Canadian children for exams, cleanings, X-rays, fillings, and other basic services, and Brampton Smiles is a participating CDCP provider. Most extended dental plans cover children’s preventive care at a high percentage and fillings under basic services.
We confirm coverage before treatment and give you a written estimate, so you know your share before the appointment. Brampton Smiles direct-bills on the day of treatment. See CDCP details.
“The single most useful question I ask a parent is not what their child eats. It is how often. A child who has one dessert after dinner is in far better shape than a child who sips juice through the afternoon, even if the total sugar is identical. Changing the frequency is usually the whole intervention.”
Frequently Asked About Dental Cavities at Brampton Smiles
Can a cavity be reversed without a filling at Brampton Smiles?
Sometimes. A very early lesion where the enamel surface is still intact can often be remineralized with professionally applied fluoride varnish, better brushing, and less frequent sugar exposure. Once the surface has broken and there is a genuine hole, a filling is required. Dr. Azher Abbas, DMD, will tell you honestly which stage your child is at.
Why does Brampton Smiles fill baby teeth that will fall out anyway?
Because untreated decay in a baby tooth can reach the nerve, abscess, and damage the permanent tooth developing directly underneath it. Losing a baby molar early also costs the space the permanent premolar needs, which often leads to orthodontic problems. Treating the tooth is almost always less disruptive than losing it early.
Does Brampton Smiles use mercury fillings for children in Brampton?
No. Brampton Smiles places tooth-coloured composite restorations and does not place new amalgam. Composite bonds to the tooth, requires less removal of healthy structure, and matches the surrounding enamel. For a baby molar with extensive decay, a prefabricated crown is often a more durable choice than a large filling.
My child is terrified of the dentist. How does Brampton Smiles handle that?
We book longer appointments so nothing is rushed, show and explain each instrument before it is used, and agree on a hand signal that stops treatment immediately. For very anxious children we offer a no-treatment introductory visit first, and oral sedation is available where appropriate. Parents are welcome in the room with younger children.
How often should my child be checked for cavities in Brampton?
Every 6 months for most children, starting with a first visit by age 1. Children with a history of decay, deep grooves, orthodontic appliances, or dry mouth may be seen more often. Brampton Smiles offers appointments until 8 PM on Monday, Wednesday, and Thursday, plus alternating Saturdays, so visits fit around school.
