Common Orthodontic Problems in Children: What Parents Should Watch For!

A healthy smile starts early! Some orthodontic issues can be easier to correct when identified during childhood. Common signs to look for include:

✔️ Crowded or overlapping teeth
✔️ Early or late loss of baby teeth
✔️ Difficulty chewing or biting
✔️ Mouth breathing
✔️ Thumb sucking beyond age 4–5
✔️ Teeth that don't meet properly when biting
✔️ Protruding front teeth

The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age 7. Early assessments can help detect developing problems and determine the best time for treatment.

At St Louis South Orthodontics, we're dedicated to helping children achieve healthy, confident smiles that last a lifetime. If you have concerns about your child's teeth or bite, our team is here to help.

Is Crossbite affecting your smile? We can help!

A crossbite occurs when some of the upper teeth sit behind the lower teeth when biting down, instead of fitting properly over them. This common orthodontic issue can affect one tooth or multiple teeth and may lead to uneven tooth wear, jaw discomfort, chewing difficulties, and changes in facial growth if left untreated.

At St Louis South Orthodontics, we offer personalized crossbite treatment to help correct bite alignment, improve oral health, and create a more balanced, confident smile.

Benefits of Crossbite Treatment:

Proper bite function
Improved jaw alignment
Reduced wear on teeth
Better long-term oral health
Lowers risk of gum recession around affected teeth
A healthier, more confident smile

Early evaluation can make a significant difference in treatment outcomes. If you’ve noticed your child's teeth don't line up correctly, we're here to help.

Contact St Louis South Orthodontics today to schedule a consultation and learn about the best treatment options for your smile!

Teeth moving after Invisalign even with retainer!

Teeth can still move after Invisalign even if you wear your retainer consistently. Some minor shifting is normal because teeth naturally settle over time, especially in the first year after treatment. Retainers help maintain results, but they can lose effectiveness as they wear out.

Common reasons include:

Not wearing the retainer enough hours
A retainer that’s warped, cracked, or stretched out
Teeth grinding or clenching at night
Natural bite and jaw changes over time
Missing retainer wear for even short periods

You should see your orthodontist if:

Your retainer feels noticeably tighter
It no longer fits fully
Crowding or gaps are coming back
Your bite feels different
You notice visible tooth movement

Catching it early usually makes it easier to fix — sometimes with a new retainer or a short refinement instead of restarting treatment.

Schedule an appointment if you experience any of the above or to begin your while new smile journey with us!

Adjusting to life with braces becomes much easier with proper care, healthy habits, and the right guidance!

Keeping your braces clean is one of the most important parts of your smile journey. Be sure to brush after every meal, floss daily, and use any special tools recommended by your orthodontist to help clean around brackets and wires. Good oral hygiene helps keep your teeth and gums healthy throughout treatment.

Choosing the right foods can also make a big difference. Soft foods like yogurt, pasta, mashed potatoes, smoothies, eggs, and soups are great options — especially after adjustments. Avoid sticky, hard, or crunchy foods like popcorn, caramel, gum, nuts, and hard candies, as they can damage brackets and wires. Cutting fruits and veggies into smaller pieces can also help protect your braces.

Every adjustment brings you one step closer to a healthier, more confident smile! At St Louis South Orthodontics, we’re here to support you every step of the way.

A little expansion can make a BIG difference! - E Arch expander!

E-Arch expander is often used as part of treatment to gently widen the upper arch—creating the space needed for proper alignment and a healthier bite. It’s a simple, effective step that can help reduce crowding and guide your smile into its best position.

Every smile is unique, and our team at St Louis South Orthodontics customizes each treatment for the best results possible!

Have questions or wondering if it’s right for you or your child? We’d love to help.
