According to the American Dental Association (ADA), if the baby quits thumb sucking before they get their permanent teeth, it is most likely that thumb sucking will not cause your teeth problems. However, it is better to start now than to wait.
Permanent teeth may start coming in around 6 years of age. Not only do you want to preserve the health of your child's permanent teeth, but you also want to preserve the health and safety of your child. It is better to start the process now. You can also quit sucking thumb habit of your child by visiting the Amazon Australia website. Here is some advice to help you along the way.
(1) First of all, talk to your child. Explain that young children do not suck their thumbs and doing so will spoil their beautiful (girls) or handsome (boys) teeth. Try to keep a Band-Aid on your thumb to remind them.
(2) An old school method is to paint your child's thumb with lemon juice or bitter solution. If your child sucking his thumb in his sleep, try to put socks on their hand at bedtime.
(3) Another great way is to praise your child. If you see your child without his thumb in his mouth, make a big deal out of it. You can also offer a small reward if you choose.
If all else fails, call your family dentist. They may suggest an over-the-counter solution. Remember, if your child is a few years from the age of 6, you still have time. Just make sure that you want to help your baby quit sucking the thumb, rather than later.
