Self-ligating braces in Barcelona
A self-ligating bracket is an ordinary bracket with a clip: the archwire is held by that clip instead of by the elastic tie that has to be changed at every visit. That shortens the appointment and makes cleaning around the bracket easier. What it does not do, and it is what gets claimed most about them, is shorten the treatment.
What they are and how they differ
A self-ligating bracket is an ordinary bracket with a lid. In conventional braces the archwire is held to the bracket by an elastic or a fine wire tie that has to be changed at every adjustment; here the bracket itself carries a clip that closes over the wire and holds it in place. That is the whole difference, and it changes several things about daily life with braces.
They are fitted like any fixed appliance, on the outer face of the tooth, and they come in steel and in tooth-coloured ceramic. That is worth knowing because it is often confused: self-ligating does not mean discreet. A metal self-ligating bracket looks like any other metal bracket; the one that blends in is the ceramic version, and that one costs more.
What this page will not tell you is that they shorten treatment. That is the claim you usually read and it is not established: the timeline is set by your case and by not missing adjustments. What does change, noticeably, is everything to do with the elastics.
How the clip works, and what changes for you
The elastic that holds the wire looks like a detail and it causes three of the everyday annoyances of the treatment. Removing it shows up here:
The adjustment visit is shorter. No elastic has to be taken off and put back tooth by tooth: the clips open, the wire is changed, the clips close. A ten-minute visit instead of twenty.
Nothing stains between visits. Clear elastics take on colour from coffee, red wine or curry and look yellowish within a week. With no elastics there is nothing to yellow, and on a ceramic self-ligating bracket that is precisely what keeps it discreet.
Fewer places for plaque to gather. The rim around the elastic is the hardest part of a bracket to brush. The clip leaves a cleaner surface and brushing goes faster.
The hold does not slacken on its own. An elastic loses tension over the weeks; the clip holds the same on the last day before an adjustment as on the first.
The clip itself can fail, and that is a new kind of fault. A clip that breaks or stays open cannot be seen from outside, so it has to be reported so it can be replaced.
What you gain with them
Less chair time at every adjustment. Added up over a two-year treatment that is a good number of hours of your time.
Easier to keep clean. Without the rim around the elastic, brushing around the bracket is more direct, and that lowers the risk of the white demineralisation marks that do not go away when the braces come off.
The look stays stable throughout. What yellows on braces are the elastics; without them, what you see in the final month is what you saw in the first.
They are genuinely fixed appliances. Bonded on, working twenty-four hours a day, moving teeth in any direction, without depending on you remembering to wear anything.
What to weigh against it
They cost more than conventional brackets. The bracket is more expensive to make. The figure for your case comes out of the assessment, as a fixed quote before anything starts.
They do not shorten treatment. It is the most repeated claim about them and the least supported. If you choose them expecting to finish sooner, the expectation is the wrong one; choose them for the short visits and the hygiene.
They are slightly bulkier. The clip adds volume, so they rub the lip a little more in the first days. Wax handles it.
The clip is one more part that can fail. If it opens or breaks, that tooth stops working until it is replaced, and it cannot be seen from outside.
If you also want them discreet, you need the ceramic version. Metal self-ligating brackets look like any metal bracket, and the ceramic version adds that material’s price and brittleness.
Frequently asked questions
What are the elastics on braces for?
With braces there are two different kinds of elastic. The first is the small elastic ring around each conventional bracket that ties the archwire into its slot: it is the one changed at every adjustment visit, and the one a self-ligating bracket replaces with its lid.
The second are intermaxillary elastics, which run from an upper bracket to a lower one and which you put on yourself. They pull one arch against the other to correct the bite, for example when the upper teeth sit well ahead of the lower ones.
A 2013 systematic review concludes that they do correct that kind of bite, and in a study of 366 patients not wearing them as prescribed made treatment longer. Self-ligating braces do not do away with them: if your case needs them, they are used just the same.
What can I eat with self-ligating braces, and what should I leave for later?
While your teeth are sore, in the first days, soft food is easier to manage: creamed soups, purées, rice, pasta, eggs, fish or ripe fruit. Once that phase is over you can eat almost anything, cutting up what you would normally bite with your front teeth, such as an apple or a sandwich.
What you should avoid throughout treatment is what the NHS advises against with any brace: hard and crunchy things, such as ice or whole nuts; sticky things, such as chewy sweets; and chewing gum, which gets caught. Go easy on sugary food as well, because with the appliance on it encourages tooth decay.
What happens if I swallow a bracket?
Usually it follows the same path as food: in the records of two dental hospitals, almost all the objects swallowed by accident ended up in the digestive tract and very few in the airways. Blunt pieces, such as a crown, passed on their own within one or two weeks, while pointed ones, such as a piece of wire, had to be removed by endoscopy.
Even so, do not assume it is over: go to an emergency department if you cannot stop coughing, find it hard to breathe, feel something stuck when you swallow or have abdominal pain, because a 2025 case review points out that a swallowed object can cause problems anywhere in the digestive tract.
If you have no discomfort, call us: we will decide with you whether anything needs checking and replace the bracket.
Which braces are better: metal, ceramic, lingual or self-ligating?
None of them wins on every count: the four types move teeth on the same principle, and what changes is what matters to you. If budget and strength come first, metal braces. If you want them to go unnoticed in a conversation, ceramic braces, in exchange for a more brittle material.
If you want nothing to show from the front, lingual braces, which go behind the teeth and bother the tongue more at first. And if you value shorter adjustment visits and no elastics turning yellow, self-ligating braces, bearing in mind that they do not shorten the timeline. At the assessment we tell you which ones your case allows.
Do self-ligating braces shorten treatment or hurt less?
These are the two promises you read most often, and neither holds up against the studies available. A 2013 meta-analysis found no difference from conventional braces in initial pain, in the number of appointments or in total duration, and a 2018 review of clinical trials did not find them more efficient either.
What research does support is less time in the chair at each visit. If we suggest them to you, it will be for that and for the absence of elastics, not to finish sooner.
