Concerned About My Son's Baby Bottle Tooth Decay: Can it Affect His Future Teeth?

Ans: Hello
This type of tooth decay is rather common in children. Most parents dismiss it as inconsequential because "milk teeth fall off anyway" and do not seek professional advice. I am happy to note that you are concerned and have already consulted a couple of dentists.
As long as your son's decayed teeth are asymptomatic, I would agree with your local dentists that, for now, no procedures should be done.
The logic is simple. A visit to the dentist is stressful even for adults. I imagine it would be even more so for a child of 4 or 5!
If the teeth in question are free from pain or underlying infection, we (the dental fraternity) would rather not expose the child to procedures which could potentially instill in him a lifelong fear of dentists and dental clinics.
However I strongly urge you to take your child for periodic check ups to ensure the decay doesn't spread unchecked and/or can be treated in time if the need arises. Please note if these teeth get infected and the infection is left untreated, the permanent teeth can also get damaged.
Also, you (the parent) need to inspect the said teeth and surrounding gums regularly to spot gum boils or swellings. If you spot any of this or if the child complains of pain please consult your dentist at once.
It goes without saying that he should brush his teeth with even more care. Ideally after every meal. Children cannot be fully trusted to brush their teeth well, so it's always wise for a parent to supervise.
If your son is a fussy eater you could consider giving him Calcium supplements. This will not help his current teeth in any way, but the permanent teeth which are due to erupt a few years later will hopefully be more resistant to decay.
Hope this answers your question.
