Consequences of thumb sucking:

Protruding Front teeth

When sucking their thumb, children often press their thumb against the part of the gum where their incisors emerge. Over time, this continuous pressure pushes the front teeth forward when they grow. Protruding front teeth are aesthetically unappealing and may make your child feel insecure about their appearance.

Open Bite

This means the two sets of teeth don’t touch even when your child shuts their mouth. It also causes irregular chewing pattern and discomfort.

Increases Vulnerability to Mouth Ulcers

Children that suck their thumbs are more likely to develop mouth ulcers. Mouth ulcers can make a child avoid tooth brushing because it’s painful.

Promotes Mouth Breathing

When children suck their thumb during bedtime, then they fall asleep, they’ll likely sleep with their mouths open. This makes them breathe through their mouths instead of their noses. Mouth breathing can be dangerous because it introduces harmful pathogens that can harm the teeth and gums.

Increases Risks of Infections

One of the significant problems associated with thumb-sucking is the spread of bacteria and infection into a child’s body, weakening the immune system to fight against the bacteria and germs affecting oral and overall health.

Misalignment of Jaw and Teeth

The most negative side-effect of thumb-sucking is to cause misalignment of a child’s teeth and even jaw.

Sensitivity Issue in The Mouth

Another risk associated with thumb-sucking is damaging the nerves of the gum and teeth, creating sensitivity around the mouth and teeth with a hot and cold temperature contact such as hot tea, cold drinks, soup, etc.

All these consequences are preventable and treatable, if identified and assisted at the right age.

Tooth decay in infants and toddlers is referred to as baby bottle tooth decay or nursing bottle caries.Though the name suggests it is caused exclusively by bottle feeding, it can occur in breast infants too if the correct technique of feeding is not followed. This type of decay typically affects upper front teeth though other teeth may be affected too.

Childhood Teeth Decay Stages


The cause of this characteristic pattern of decay are sweetened liquids or those with natural sugars (like milk, formula, and fruit juice) being in prolonged contact with an infant’s teeth for a long time. Bacteria in the mouth grow rapidly on this sugar and make acids that attack the teeth and destroy it completely over time.

One common risk factor is the frequent, prolonged exposure of the baby’s teeth to drinks that contain sugar. Tooth decay can occur when the baby is put to bed with a bottle or when a bottle is used as a pacifier for a fussy baby.

If baby bottle tooth decay is left untreated, pain and infection can occur which may result in abscess formation and even need hospitalization to treat the infection. If teeth are taken out early without precautions to maintain their space,the child may develop poor eating habits, speech problems, crooked teeth, and damaged adult teeth.
