Special Appliance Instructions
Care and wear guides for every orthodontic appliance we use at Oliver Orthodontics
Your Appliance Instructions, All in One Place
Special orthodontic appliances are powerful tools for guiding jaw growth, correcting bites, and creating space for permanent teeth. Used correctly, they dramatically reduce or eliminate more complex treatment later.
Select your appliance below for complete wear, care, and cleaning instructions. If you are unsure which appliance you have, call us and we will help you identify it.

Palatal Expander
Upper jaw widening device
What it does
A palatal expander widens the upper jaw (maxilla) to create more space for teeth, improve the bite, and expand the airway. It works best in growing patients because the two halves of the palate have not yet fused.
How it works
The expander is bonded to your upper molars and has a small screw in the center. Activating the screw a tiny turn each day (or as prescribed) gradually separates the two halves of the palate, allowing new bone to fill in the gap. The process is slow and painless.
Wear Instructions
How to Clean
What to Expect
You may experience mild pressure or soreness after each activation — this is normal and usually passes within a few minutes. Speech may be slightly affected at first but improves quickly. A gap between the front teeth is normal and expected during active expansion.
When to call us: Call us if you notice the expander feels loose, if there is significant pain rather than mild pressure, or if you lose the key.
Herbst Appliance
Lower jaw positioning device
What it does
The Herbst appliance corrects overbites (where the upper teeth and jaw protrude significantly beyond the lower) by positioning the lower jaw forward during growth. It is a fixed appliance worn 24 hours a day.
How it works
Metal tubes and rods connect the upper and lower jaws in a slightly forward position. This constant gentle positioning encourages the lower jaw to grow forward while restraining excess growth of the upper jaw. It is most effective in growing patients.
Wear Instructions
How to Clean
What to Expect
Your cheeks and tongue need a few weeks to adapt to the hardware inside your mouth. Mild jaw soreness is normal initially. You may notice changes in how you chew — softer foods are recommended during the adjustment period.
When to call us: Call us if a tube or rod comes loose, if there is significant jaw pain rather than mild soreness, or if the appliance appears bent or broken.
Headgear
Jaw growth guidance appliance
What it does
Headgear applies gentle force to guide the growth of the jaw and facial bones in growing patients. It is most commonly used to restrain upper jaw growth in patients with a significant overbite, or to help close spaces and move back teeth.
How it works
Headgear attaches to hooks on your upper molar bands via a facebow (a U-shaped wire), and connects to a strap that wraps around the back of your head or neck. The force from the strap gently holds the upper jaw from growing too far forward relative to the lower jaw.
Wear Instructions
How to Clean
What to Expect
Some pressure and mild soreness when first wearing headgear is normal. This typically passes within a few days. You will adapt quickly, and most patients find it easy to sleep with headgear on after the first week.
When to call us: Call us if the facebow bends, if the molar bands feel loose, or if you experience unusual pain or discomfort.
Twin Block Appliance
Removable jaw repositioning device
What it does
The Twin Block is a removable functional appliance that positions the lower jaw forward to correct overbites and encourage proper jaw growth. It consists of upper and lower plates with angled blocks that fit together when the mouth is closed.
How it works
When you bite down, the angled blocks on the upper and lower plates guide the lower jaw into a forward posture. Worn consistently during growth, this trains the jaw muscles and stimulates bone growth in the lower jaw while restraining the upper.
Wear Instructions
How to Clean
What to Expect
Initial soreness in the jaw and teeth is common during the first 1–2 weeks as your muscles adapt to the new jaw position. Speech changes at first are normal — you will sound more normal quickly. Stick with it: consistency is everything with functional appliances.
When to call us: Call us if the appliance cracks, if a block or wire comes loose, or if you experience significant pain rather than the normal adjustment soreness.
Rubber Bands (Elastics)
Bite correction elastic bands
What it does
Elastics are small rubber bands worn between hooks on your upper and lower braces or aligners to correct the relationship between your upper and lower teeth — improving bite alignment, fixing overbites, underbites, and crossbites.
How it works
By connecting upper and lower teeth in specific patterns, elastics apply continuous gentle force that moves your jaws and teeth into proper alignment. The specific hooking pattern and elastic size are prescribed by Dr. Oliver based on your bite needs.
Wear Instructions
How to Clean
What to Expect
Your jaw and teeth may feel sore for a few days when you first start wearing elastics, and again after each change in pattern. This is normal. You may also notice some jaw fatigue initially — this passes quickly. The results from consistent elastic wear can significantly shorten your overall treatment time.
When to call us: Call us if you run out of elastics, if you are unsure of your hooking pattern, or if you notice a hook on a bracket has broken off.
Space Maintainer
Tooth space preservation device
What it does
A space maintainer holds open the space left by a prematurely lost baby tooth. When a baby tooth is lost too early, neighboring teeth naturally drift into that space — preventing the permanent tooth from erupting properly. A space maintainer preserves the space until the permanent tooth is ready.
How it works
Space maintainers are typically fixed metal bands and wires bonded to teeth on either side of the gap. They hold the space open passively — the appliance does not move teeth, it simply stops adjacent teeth from moving into the space.
Wear Instructions
How to Clean
What to Expect
A space maintainer should not cause significant discomfort after the initial brief placement appointment. Your child's tongue may play with the wire at first — this is completely normal and passes quickly.
When to call us: Call us immediately if the appliance comes loose, feels sharp, or if your child is having difficulty eating. Time is critical when a maintainer comes off — teeth drift fast.
Tips for Every Appliance Patient
🦷
Hygiene is critical — appliances create many extra surfaces for plaque to hide. Brush and rinse after every meal.
🚫
Avoid the foods on the foods-to-avoid list — hard and sticky foods are especially damaging to appliances.
📋
Bring your appliance (if removable) to every appointment, even if you think it looks fine.
📞
If something feels wrong — loose, broken, or poking — call us rather than waiting for your next scheduled visit.
💬
Speech adapts. Most patients are speaking normally within one to two weeks of getting a new appliance.
💊
Soreness at first is normal. Over-the-counter pain relievers and soft foods help during the first few days.
Something Does Not Look Right?
Never wait when something seems off with your appliance. Most issues are simple fixes — but only if we catch them quickly
