There are five main types of braces used in orthodontics today: traditional metal braces, ceramic braces, lingual braces, self-ligating braces, and clear aligners. Each works differently, costs differently, and suits different levels of complexity. Most people wear braces for 18 to 24 months, though that range shifts depending on which type you choose and how much correction your teeth need.
Traditional Metal Braces
Metal braces are the most common and most versatile option. They use three components: small metal brackets bonded to each tooth, an archwire threaded through those brackets, and tiny elastic ties (called ligatures) that hold the wire in place. The archwire applies steady pressure, and your orthodontist tightens or replaces it at regular appointments to keep teeth moving in the right direction.
Metal braces are considered the standard of care for severe crowding, significant overbites, and complex bite issues. They provide consistent, strong pressure that other options sometimes can’t match. Treatment typically runs 18 to 24 months for moderate cases and 24 to 36 months for severe crowding or bite correction. Cost ranges from $3,000 to $7,000.
The main downside is visibility. Metal brackets and wires are obvious when you smile or talk. They also require careful cleaning, since food gets trapped around brackets and under the archwire easily. An interproximal brush (a small, pointed brush designed to fit between brackets) and a floss threader are essential daily tools.
Ceramic Braces
Ceramic braces work exactly like metal braces but use brackets made from a clear or tooth-colored ceramic material. From a few feet away, they blend in with your teeth far better than metal. This makes them a popular choice for adults and teens who want fixed braces without the metallic look.
The ceramic brackets themselves don’t stain easily, but the small elastic ties holding the wire to the brackets do. These ties can pick up color from coffee, tea, red wine, and certain foods, and they stay stained until your orthodontist replaces them at your next visit. If staining bothers you, you’ll want to be mindful of what you eat and drink between appointments.
Ceramic braces handle most of the same orthodontic problems metal braces do, with a similar treatment timeline. They cost a bit more, typically $4,000 to $8,500, because the ceramic material is more expensive to manufacture. Ceramic brackets are also slightly more fragile than metal, so your orthodontist may recommend metal for the lower teeth (where bite force is higher) and ceramic for the upper teeth where they’re more visible.
Lingual Braces
Lingual braces use the same brackets-and-wire system as traditional braces, but everything is attached to the back surfaces of your teeth instead of the front. That means they’re essentially invisible when you smile. For people who need the corrective power of fixed braces but don’t want anyone to see them, lingual braces offer a unique solution.
The trade-off is comfort and speech. When you talk, your tongue naturally touches the backs of your teeth to form certain sounds. With brackets sitting on those surfaces, you should expect a noticeable lisp for the first few weeks or even months. Research from 2014 found that speech changes can persist for a month or more before your tongue fully adapts. The brackets can also irritate the tongue itself, especially early in treatment.
Lingual braces are the most expensive option, running $8,000 to $10,000. They also require an orthodontist with specialized training, since placing and adjusting brackets on the tongue side of teeth is technically demanding. Not every orthodontic office offers them.
Self-Ligating Braces
Self-ligating braces look similar to traditional metal braces but eliminate the elastic ties. Instead, each bracket has a built-in clip that holds the archwire in place. This is a small mechanical difference with practical consequences.
In traditional braces, the elastic ties press the wire firmly into each bracket slot, creating friction. That friction is resistance the tooth has to overcome before it can move. Self-ligating brackets, particularly the “passive” variety, use a clip that holds the wire loosely, allowing it to slide with minimal friction. The idea is that lighter forces and less resistance let the natural process of bone remodeling proceed more smoothly, potentially meaning less discomfort at adjustments.
Self-ligating systems are available in both metal and ceramic versions. Because there are no elastic ties to replace, appointments can be shorter and spaced further apart. Cost is generally comparable to or slightly higher than traditional metal braces. These braces handle the same range of orthodontic problems as conventional fixed braces.
Clear Aligners
Clear aligners are removable plastic trays custom-molded to your teeth. You receive a series of trays, each slightly different, and swap to a new set every one to two weeks. Each tray nudges your teeth a fraction of a millimeter closer to their target position. Invisalign is the best-known brand, but several companies now offer similar systems.
The biggest practical requirement is wear time. Aligners need to stay in your mouth for at least 20 hours per day to be effective. You remove them only to eat, drink anything other than water, and brush your teeth. People who forget to put them back in or wear them inconsistently see slower results or results that don’t match the original treatment plan.
Clear aligners work well for mild to moderate crowding and spacing issues. For mild crowding, treatment can wrap up in 6 to 12 months, compared to 12 to 18 months with traditional braces for the same problem. Moderate cases typically take 12 to 18 months in aligners. However, aligners have real limitations: they can’t correct severe crowding reliably, struggle with significantly rotated teeth, and don’t provide enough force for major bite correction. Orthodontic problems caused by jaw positioning rather than tooth positioning are better treated with fixed braces or other appliances.
Cost ranges widely, from $1,000 to $8,500, depending on the brand and complexity of your case. Simpler cases using direct-to-consumer aligner companies sit at the lower end, while comprehensive treatment through an orthodontist’s office falls closer to the higher end.
How Complexity Affects Your Options
The right type of braces depends largely on how much correction your teeth and bite need. Here’s how the options line up across common conditions:
- Mild crowding or spacing: All five types work well. Clear aligners offer the shortest treatment time (6 to 12 months) and the most discreet experience.
- Moderate crowding: Metal, ceramic, self-ligating, and lingual braces all handle this reliably in 18 to 24 months. Clear aligners can work but take 12 to 18 months and may require attachments (small tooth-colored bumps bonded to teeth) to grip effectively.
- Severe crowding or significant bite issues: Traditional metal braces remain the gold standard. Treatment runs 24 to 36 months. Clear aligners are often not suitable, and lingual braces may be an option if your orthodontist has the expertise.
- Overbite correction: Traditional braces are the preferred choice for severe overbites. Clear aligners can address minor to moderate overbites but don’t deliver consistent enough pressure for severe cases.
Cost at a Glance
- Metal braces: $3,000 to $7,000
- Ceramic braces: $4,000 to $8,500
- Self-ligating braces: Similar to metal or slightly higher
- Lingual braces: $8,000 to $10,000
- Clear aligners: $1,000 to $8,500
Most dental insurance plans with orthodontic coverage contribute a fixed amount (often $1,000 to $2,000) regardless of which type you choose. Many orthodontic offices also offer monthly payment plans that spread the remaining balance over the length of treatment.
Caring for Your Braces
Oral hygiene matters more during orthodontic treatment than at any other time, because brackets, wires, and aligners all create new places for plaque and food to hide. The American Association of Orthodontists recommends brushing and flossing after every meal, not just morning and night.
For fixed braces (metal, ceramic, lingual, or self-ligating), an interproximal brush is essential for clearing food from around brackets and under the archwire. A floss threader or pre-threaded orthodontic floss lets you clean between teeth despite the wire blocking normal flossing. Orthodontic wax is useful for covering any bracket or wire that irritates your cheeks or tongue. When you can’t brush right away, swishing with plain water after eating helps remove food particles and reduce acid buildup.
Clear aligners simplify cleaning in one way: you remove them to brush and floss normally. But the trays themselves need daily cleaning too, since bacteria build up on the plastic. Rinsing them every time you take them out and brushing them gently with a soft toothbrush keeps them clear and odor-free.
