Block braces: Pros, cons & what to expect

If you've been thinking about getting orthodontic treatment and someone has mentioned block braces, you might be wondering, “What are they, and how do they work?” Block braces, also called removable orthodontic appliances, have become a go-to functional braces for jaw alignment in kids and teens. This guide will break down how they function, their pros and cons, and what to expect before, during, and after treatment.

Understanding block braces

Block braces are removable devices used mostly in children and teens to fix jaw misalignments, especially when the upper teeth stick out far beyond the lower ones (Class II malocclusion).
Unlike the usual fixed metal braces, block braces are not fixed to the teeth. Instead, they're made of tough acrylic and metal, and can be taken in and out. The top and bottom parts work together to gently guide the jaw into the right position.
They don't just straighten teeth, they help align the jaw, encouraging proper facial and bite development as the child grows.

How do block braces work?

You must be thinking, how do block braces actually work?

Two plates

The braces include upper and lower pieces that fit into the mouth and work together when you bite down.

Muscle training

When you close your mouth, the brace applies light pressure to the jaw muscles, encouraging them to move the jaw into the correct place over time.

Guided growth

These braces take advantage of natural growth in children, helping to guide jaw development during key growth stages.

Wear time

To work properly, they usually need to be worn 12-16 hours a day, often overnight.

Who should use block braces?

They're typically recommended for:

• Kids aged 8-14, when the jaw is still growing

• Patients with an overbite or significant difference between upper and lower jaw growth

• Those who could benefit from early treatment before getting fixed braces

While they work best in growing kids, some adults with mild jaw misalignments might also benefit, though they're not always the only treatment needed.

Advantages of block braces

Here's why many orthodontists and families choose block braces:

Fixes the jaw, not just teeth

They tackle alignment issues that could otherwise lead to jaw pain, speech problems, or long-term dental complications.

Easy to maintain

Since they're removable, it's easier to brush and floss properly, helping avoid cavities or gum issues.

Comfortable and non-invasive

There are no brackets or wires to poke or irritate the mouth. Once patients adjust, they often find it easier to wear.

Great for early action

Starting treatment early can reduce the need for surgery or more intense orthodontics later.

Encourages natural growth

They work with the body's development, often avoiding the need for extractions or surgery.

Disadvantages of block braces

Still, they're not perfect. Here are a few things to keep in mind:

Adherence to wear time

Because they're removable, they only work if worn consistently. Skipping hours can delay results.

Not suitable for severe cases

Adults or those with major alignment problems may need a different approach, like fixed braces or surgery.

Initial discomfort

They can feel bulky at first, and some kids find them uncomfortable early on.

May affect speech

It's common to notice a temporary lisp or speech changes in the beginning.

Limited for tooth alignment

They mainly focus on the jaw, so braces might still be needed later to straighten teeth fully.

Are block braces painful?

A common question is whether block braces hurt. The answer? Not really. Unlike metal braces that pull constantly on the teeth, block braces gently encourage jaw movement. Still, you might feel:

• Soreness when they're first fitted

• Pressure as your jaw shifts

• Some tightness during growth spurts

Most describe it more as a dull pressure or tight feeling, not sharp pain. It usually fades after a few days of consistent wear.

How to stop braces pain

Here are some tips on how to stop braces pain in the first week.

• Wear them regularly to help your mouth adjust

• Stay away from chewy or hard foods

• Ask your orthodontist about using over-the-counter pain relievers if needed

Block braces treatment duration

Before getting your treatment started, you must be wondering how long does it take to put braces on and what their treatment duration is. Block braces are not fitted on the surface of teeth, which means they might not take as long to get fitted. Moreover, the average treatment duration is 12 months by adhering to the wear time.

How to maintain block braces?

Regular cleaning

Use a soft-bristled brush and lukewarm water to clean your block braces before and after use. Do not use a hard-bristle brush and hot water, as it can damage or warp the appliance.

Proper storage

If you are not wearing them, make sure to store them in a well-ventilated container. Do not wrap your braces in a napkin or keep them in your pocket or purse without proper storage.

Avoid hard and sticky foods

Try to avoid hard and sticky foods as they can cause damage to the braces.
