Despite our common parental assumption that cavities are an “adult problem,” 1 in 5 children between the ages of 5 and 11 have at least one untreated cavity (CDC). We underestimate how important baby teeth are, and decay left untreated can cause discomfort, infections, and even damage to adult teeth. So, when is a filling actually necessary for your child? Let’s find out!
Why Do Children Get Cavities?
Cavities develop when sugar and bacteria combine to produce acid that erodes tooth enamel. Decay results from this acid’s gradual dissolution of the teeth’s outer layer of defense. The main culprits are:
Sugary foods and beverages: Even those that look healthful, such as fruit juice or raisins, are common causes of cavities. Since sticky foods stay on teeth longer, germs have more opportunity to create dangerous acid.
Bad brushing practices: Children usually neglect difficult-to-reach back teeth, which leads to the accumulation of plaque. Additionally, when children sleep with milk or formula, their teeth are exposed to sugar for the duration of the night, which can lead to bottle decay.
Genetics: Certain children’s teeth are more susceptible to cavities because their enamel is inherently weaker.
Signs Your Child Might Need a Filling
Here are a few warning indicators that your child may need a filling:
Visible Holes
There are obvious warning indicators if your child’s teeth have visible gaps or dark patches. Developing deterioration that requires treatment is frequently indicated by brown, black, or white spots.
Pain or Sensitivity
A cavity may be developing if your child complains of dental discomfort or sensitivity, particularly while consuming hot, cold, or sweet foods. Pay attention to these discomforts.
Avoiding Chewing on One Side
If your youngster habitually chews on one side, take note. This odd behavior might indicate that they are avoiding a tooth on the other side that hurts.
Bad Breath
Bad breath that doesn’t go away after brushing may indicate an illness or decay that is lurking beneath the surface.
Many cavities start between teeth where you can’t see them. Only a dentist can detect these with proper examination tools.
How Can You Prevent Cavities in Children?
You can use the following tips to prevent cavities in your child:
- Use fluoride toothpaste to brush twice a day to help build youthful enamel.
- Sticky candy should be replaced with tooth-friendly alternatives like cheese cubes, yogurt, or crisp vegetables.
- When the child is one year old, or when the first tooth erupts, schedule an initial dental appointment. Maintain a biannual cleaning schedule to identify any problems early on and address them.
- Discuss fluoride treatments to strengthen enamel and protective sealants for those rear molars that are prone to cavities for an extra line of defense.
Summing Up!
Cavities are a common problem in many children’s lives. While it’s hard to stop your child from eating their favorite snacks, you can still prevent cavities by taking good care of their dental health. However, if it happens, your child may need a dental filling to preserve a healthy, radiant smile.
