Can Teeth Straighten As You Grow?

Can Teeth Straighten As You Grow?

If your child's teeth start to grow crooked or crowded you might be wondering if you have to get them to an orthodontist or if they will straighten out as your child ages. Our Burnaby orthodontists are here to talk about it

Causes Of Crooked Teeth

Crowded teeth don't just happen to adult teeth. Your child's primary or baby teeth can grow crooked for a number of reasons. These primary teeth can grow in crooked simply because they are too small to fill the space along the jaw, or they can be the result of prolonged habits such as sucking on a pacifier or thumb. Heredity and genetics may also play a role.

If your child's teeth are crooked this does not necessarily indicate that their permanent teeth will end up that way too. With this being said, however, if baby teeth are getting crowded, it is likely that the permanent teeth will be as well. 

Other causes include jaw size, malocclusion, genetics, poor dental care and nutrition, and trauma. 

Can a child's crooked teeth straighten as they grow in?

A child's front permanent teeth may angle away from the center and appear misaligned. This is normal, and the teeth should straighten out naturally once the permanent teeth start to come in.

children's baby teeth start to fall out at about 5 years of age. The last of which should be gone by about age 12. Parents often worry if they start to notice their child's permanent teeth looking crooked, and while it is possible that they may require orthodontic intervention, it is important to remember that their smiles are still developing. Some crookedness may even out on its own. 

Ideally, a child should start having dental checkups as a toddler to prevent cavities and monitor growth and development. When this is the case, the dentist will be aware of misalignment issues before they start to cause problems.

Why Crooked Teeth Should Be Straightened

The overall look of your teeth is not the only consideration when it comes to crooked adult teeth. Misaligned teeth may also result in oral health issues depending on the severity of the misalignment. 

As soon as your child starts to speak they are at a critical age especially when it comes to having crooked or misaligned teeth as this can affect speech development. If your child can't properly close their mouth due to an overbite, they can start to have trouble breathing, especially at night. If teeth grow in too close together or are twisted in the wrong angle, it makes it hard to effectively clear them. Not brushing and flossing well means a greater chance of cavities and gum disease. 

In the worst cases, patients might have trouble chewing, jaw pain, and a condition called temporomandibular joint disorder (TMJ). 

Many people go their entire lives with crooked teeth and never develop a serious problem. There is a chance that as a child’s jaw grows, their teeth might even out and straighten on their own as their mouth and jaw grow and change. If they do not, or if the misalignment is extreme, some type of orthodontic treatment might be necessary.

How Crooked Teeth Can Be Straightened

There are a number of orthodontic techniques that can be used to help straighten your smile if it is not doing so naturally. 


Metal, ceramic, or clear aligners are the most common choice for straightening teeth for children. Lingual braces attach to the inside of the teeth, but they need enough room to adequately fit and do their job. Most kids do not have big enough teeth for lingual braces.

Some orthodontists wait until the patient is about 10 years old, but many children as young as 7 can be fitted with braces. They are the most effective tool for almost any issue of crookedness or crowding. They also can work well for correcting malocclusions.


Retainers become very important once your orthodontic treatment is over. They help keep your teeth from shifting back into the incorrect position. A retainer might be all that is necessary for some mild cases of crookedness.

Palatal Expanders

Children or adults with a “narrow smile” where the arch of their teeth is small, might need a palatal expander. The expander is attached to the back teeth and across the roof of the mouth. The device is gradually adjusted to push outward, widening the top jaw. After the jaw is expanded, braces might still be necessary to move the individual teeth into alignment. 


If you lose a tooth, it might actually contribute to causing crookedness to become worse. That being said, sometimes it is necessary to have a took extracted by a dentist in the case of extreme overcrowding and your dentists might remove baby teeth to allow an adult tooth to erupt. 


Plastic aligner trays like Invisalign can often fix mild to moderate crowding and crookedness. But aligners are not always recommended for young children. Adults and older kids who have finished growing may prefer this method, as it is removable and less noticeable than braces.
