Did you know that losing baby teeth early can affect the way permanent teeth grow?
This is where Space Maintainers help - A simple and effective dental appliance that protects the space for your child’s adult teeth, helping them grow in the right place for a well-aligned smile.
What is a Lingual Arch Space Maintainer?
A lingual arch space maintainer (LASM) is a type of space maintainer for the lower jaw - A small, custom-made wire placed behind the lower teeth. It holds the space left by missing baby teeth and guides permanent teeth to grow in the correct position.

Why Your Child Might Need One
Without a space maintainer, nearby teeth can drift into the empty space, which may lead to:
Crowded and misaligned adult teeth
Impacted adult teeth
Possible need for orthodontic treatment (braces) later

What Happens During THE PROCEDURE
The procedure is quick, gentle, and generally quite painless:
Your child’s teeth are measured and bands are fitted on the back molar teeth for size verification, followed by fabrication of the appliance in a lab
The appliance is carefully placed and adjusted for comfort in the second appointment
Note that your child may feel slight pressure for a day or two, but it does not cause pain
How to Care for the Appliance
Do:
Brush gently around the bands twice daily with fluoride toothpaste
Attend check-ups every 4–6 weeks
Schedule teeth cleaning and fluoride application every 3-6 months

Common Questions Parents Ask
Will it hurt?
No. Your child may feel some pressure for a short time, but it is not a painful process.
How long will it stay in?
Usually 1–3 years, until permanent teeth (premolars) have come in.
Can it affect speech?
Some children may have a slight lisp initially, but they get used to it quickly.
What if it comes loose?
Contact your dentist immediately to prevent any problems. In an event that the appliance dislodges, advice your child to store it safely and bring it along for the following dental appointment.
