Side Effects of Braces: What’s Normal, What’s Rare, and What’s Preventable

Updated: October 1, 2026 ·

Braces move teeth through bone. That’s a remarkable thing to ask of your body, and it comes with some side effects. Most of them are mild and temporary. A few can last, but nearly all of those are preventable.

We’d rather you hear this from us than from a forum at 2 a.m. So here’s the honest version, sorted by how long each side effect sticks around.

Quick Answer: Are the Side Effects of Braces Serious?

For the vast majority of patients, no. Expect a few days of soreness after each adjustment, some cheek irritation early on, and a learning curve with eating and cleaning. Serious or permanent side effects are uncommon. The most frequent ones (white spots and gum inflammation) come down to oral hygiene, which puts them largely in your control.

Short-Term Side Effects (Days to Weeks)

Soreness and Pressure

Your teeth will ache for two to four days after brackets go on and after most adjustments. That pressure is the sign your teeth are moving. Soft foods, cold water, and over-the-counter pain relievers (as directed on the label) handle it for most people.

Mouth Sores and Cheek Irritation

Brackets rub the inside of your cheeks and lips until the tissue toughens up, usually within a couple of weeks. Orthodontic wax is your best friend here. Press a small piece over any bracket that’s bothering you.

Speech Changes

A slight lisp sometimes shows up in the first few days, especially with appliances behind the teeth. Your tongue adapts fast. Reading aloud speeds it up.

Eating Adjustments

Sticky, hard, and chewy foods can bend wires and pop brackets loose. You’ll need to cut apples, skip caramel, and rethink popcorn. Our braces-friendly diet guide makes the switch easier.

Long-Term Side Effects (During Treatment)

Gum Inflammation

Plaque hides around brackets, and gums respond by getting puffy and bleeding when you brush. This is called gingivitis. It’s reversible with consistent brushing and cleaning between teeth. Our walkthrough on how to floss with braces covers the tools that make it doable.

Tooth Sensitivity

Some patients notice sensitivity to cold during active treatment. A sensitivity toothpaste usually helps. Tell us if it lingers.

Jaw Fatigue

Elastics (rubber bands) and bite correction can leave your jaw tired. This typically fades as your bite settles.

Permanent Side Effects of Braces (and How to Prevent Them)

These are the ones people worry about most. Here’s the truth about each.

White Spots (Decalcification)

White, chalky marks around where brackets sat are the most common lasting side effect. They form when plaque sits on enamel long enough to pull minerals out. Prevention is straightforward: brush after meals, use fluoride toothpaste, and keep up with your regular dental cleanings. Mild spots often fade after braces come off. Our guide to whitening teeth after braces explains what helps and what to avoid.

Root Resorption

Moving teeth can slightly shorten tooth roots. In most patients the change is minor and has no effect on how the teeth function. We monitor root health with X-rays during treatment and adjust forces if we see concerns.

Gum Recession

Thin gum tissue can recede when teeth move, particularly on lower front teeth. Careful treatment planning and gentle brushing lower the risk.

Teeth Shifting Back (Relapse)

This one’s 100% preventable. Teeth want to drift back to their old positions for years after treatment. Wearing your retainer as prescribed stops that. Learn the warning signs your retainer needs replacing.

Side Effects of Braces After Removal

The day your braces come off feels amazing. The next few weeks can feel strange. Your teeth may feel slippery, slightly loose, or sensitive. Gums may look puffy until they recover. All of this is normal and fades within a few weeks. The one side effect that won’t fade on its own? Shifting teeth, if you skip your retainer.

Metal Braces vs. Other Options: Do Side Effects Differ?

Soreness happens with every tooth-moving appliance, including clear aligners. What changes is the rest of the list:

If lifestyle side effects worry you, ask us about Invisalign. At BRO, it costs the same as braces.

Frequently Asked Questions

What is the most common side effect of braces?

Temporary soreness after brackets are placed and after adjustments. It usually fades within two to four days.

Can braces cause permanent damage?

Rarely. White spots and minor root shortening can last, but good hygiene and professional monitoring prevent most cases.

Do braces change your face shape?

Braces can subtly change lip support and profile, usually for the better, by improving how the teeth and jaws line up.

What are the side effects of braces after removal?

Teeth may feel loose or sensitive for a few weeks. Shifting is the one lasting risk, and wearing a retainer prevents it.
