Galway Dentist – Tooth Decay in Children

Tooth decay is the most common chronic disease affecting children. It is often referred to as:

  • Cavities
  • Tooth Rot / Rotten Tooth / Bad Tooth etc.
  • Holes
  • Staining etc.

Tooth decay is caused by the sugars we eat mixing with bacterial plaque on teeth – this creates an acid which dissolves part of the tooth. If this happens often enough cavities will occur. There are specific bacteria in our plaque that cause this condition. Because it is a bacterial disease tooth decay can spread from one tooth to another through direct contact or by shedding into the saliva exposing all of the other teeth in the mouth.

Children who experience decay of the primary teeth are more likely to experience decay in the permanent teeth. By removing tooth decay and restoring the teeth, the numbers of decay-causing bacteria are significantly reduced.

Tooth decay can also significantly affect the quality of a child’s life. If a child has a toothache or pain with chewing, they will not be able to eat properly. Growth and weight gain, sleep patterns, behaviour and school performance may also be negatively influenced.

However, tooth decay is completely preventable by:

  • Effective tooth cleaning twice a day
  • Reducing sugar intake and frequency (including natural sugars e.g. fruit, honey and manufactured sugars e.g. jellies, sweets etc.)
  • Regular visits to our dedicated Galway children’s dentist

Remember: your child can have tooth decay without any symptoms or obvious looking “cavities”.
Regular dental check-ups are very important for children.

Fixing Tooth Decay (“holes”) in Baby Teeth

Baby teeth should be retained until they fall out naturally because they serve a number of important functions. (see “why are baby teeth important“). Some children do not lose their last baby molar until 12-13 years of age. This is much later than many parents may realise.

  • If a baby tooth has a small cavity, it can be restored with a tooth coloured filling (composite).
  • If the cavity is very large or the enamel is poor quality, the tooth can be restored with a stainless steel crown. These are very successful restorations and can last many years. Children often refer to these crowns as “princess teeth” or “superman teeth”!
  • In some instances it is not possible to restore the damaged baby tooth so it will need to be extracted. However, this is a last resort as losing baby teeth early can cause loss of space for permanent teeth – this may require orthodontic treatment (braces) later.

The earlier teeth are treated the better. This is more comfortable for your child and more affordable for you.

However, it is never too late to seek dental care!

How to Prevent Tooth Decay

Tooth decay can only occur if…

Plaque (source of bacteria) + Sugar – combine to create acid which then dissolves the outer part of the tooth (enamel). Once a cavity starts it can progress rapidly – especially if there is lots of plaque and sugar around!

The good news is that there is a lot we can do both at home and in the dental surgery to stop this happening.

Prevention AT HOME

  1. Keep plaque low with good tooth cleaning twice a day (brushing morning & night; flossing at night)
  2. Keep sugar intake low.
  • Choose “healthy” foods and drinks. Water is the best and safest drink for teeth.
  • Choose “treats” that are tooth friendly; e.g. chocolate NOT sticky sweets like Skittles, Haribos, Polo-Mints etc.

Remember: the longer sugar contacts teeth (e.g. sticky toffee) and the more often sugar is taken – the higher the risk of tooth decay.

  1. Strengthen teeth by using fluoridated toothpaste. Use fluoride mouthwash if advised by dentist (usually from 6 years of age).

Prevention AT THE DENTIST

Regular dental visits greatly help to reduce the risk of tooth decay by…

  • Professional tooth cleaning – removing tartar / stains / plaque
  • Professional Fluoride – concentrated gels & varnish
  • Fissure sealants – as required
  • Periodic x-rays as needed to help detect problems early

What is Bottle Decay?

One serious form of rampant tooth decay in young children is what we used to call “baby bottle tooth decay” or “nursing caries”. We now use the term “Early Childhood Caries(E.C.C.) for this condition. The cause of this disease is a sugar-containing liquid pooling around children’s teeth for a prolonged period. Remember – all milk (human and animal) contains some sugar.

The children affected by this disease are those who typically take a bottle (containing juice, milk, formula etc.) to bed; or a child who is breast-fed on demand at night. Salivary flow and swallowing are reduced at night so teeth can be immersed in the liquid for hours! If this happens over a prolonged period (and the child’s teeth are not cleaned properly) – it is highly likely they will develop tooth decay. Top front teeth are usually the first affected – but the tooth decay can rapidly spread to other teeth.

Progression of Untreated Dental Disease in Young Children – Early Childhood Caries (E.C.C)

Losing baby teeth early can adversely affect speech / eating / appearance and the self-esteem of your child. Front baby teeth do not fall out naturally until approx. 6½ – 7½ years of age. Back baby teeth are retained much longer; early loss of these teeth can cause space loss, resulting in crowding of adult teeth – requiring orthodontic (braces) treatment later.

All this can be prevented by ensuring your child only takes PLAIN WATER to bed at night.

Left untreated, there is now further breakdown of teeth. Extensive dental treatment required.
Bottle continued – 4 top teeth now need to be removed. Treatment also required on many other decayed back teeth. If not treated there is a high risk of abscess/pain/swelling and damage to the developing permanent teeth!

Tooth decay is completely preventable. Untreated tooth decay in baby teeth can also damage permanent teeth.

How to Prevent Tooth Decay in Young Children

  • After each feeding, wipe your baby’s mouth / teeth with a damp facecloth or gauze even if baby falls asleep – this also helps get them used to tooth brushing later.
  • The only safe drink at night is water. If your child will not fall asleep without the bottle and its usual beverage, gradually dilute the bottle’s contents with water over a period of two to three weeks.
  • Stop bottles / wean breast-fed children by 1 year.

Note: Contact us if you notice any changes e.g. staining, “chipping”, or white marks on your child’s teeth. These could be signs of tooth decay; we can help you to deal with this.

In a nutshell…

Hazelnut

It comes down to basics

  1. Keep your children’s teeth clean – brushing twice a day, flossing daily
  2. Keep their total sugar intake low (Including “Natural” sugars e.g. Honey, Raisins etc.)
  3. Bring your child to the dentist regularly – approx. every 6 months or as advised by the dentist.

Regular dental check-ups save you money – problems are spotted earlier or even prevented – more comfortable for your child and easier on your wallet!
