Short answer: Braces do not cause cavities by themselves. Because brackets make cleaning harder, plaque can build up around them, and if oral care is neglected, white spots, cavities and gum inflammation can develop. Most of these risks can be prevented with proper brushing, interdental cleaning, limiting sugary foods and regular check-ups. Mild root shortening is common and is monitored by the doctor with X-rays.
One of the questions we hear most often before orthodontic treatment begins is this: do braces cause cavities? The short answer is that the brackets and wire do not decay the tooth themselves, but by making cleaning harder they can create a favorable environment for cavities and gum problems. In other words, in most cases what matters is not the presence of the braces but the oral care maintained throughout treatment. In this article we cover the risks realistically, without exaggeration, and share practical ways to reduce them.
Do braces cause cavities?
Braces alone do not cause cavities; what causes decay is bacterial plaque that stays around the brackets for a long time. A cavity forms when the acid produced by bacteria in plaque as they break down sugars gradually dissolves the enamel. This process works the same way in every mouth, with or without braces. The difference is that brackets create new surfaces for plaque to cling to and corners the toothbrush has trouble reaching.
In people who keep up regular oral care, limit sugary snacks and do not skip check-ups, treatment is generally completed without cavity problems. On the other hand, when cleaning is neglected, the most common result is dull white spots around the brackets. These spots are considered an early stage of decay; you can find the details in our article on white spots after braces.
Why does plaque build up around brackets?
Brackets, wires and sometimes elastics create small spaces where food debris and plaque can hide. In particular, the edge of the bracket facing the gum, the area between the wire and the tooth, and the surroundings of the bands on the back teeth tend to hold plaque. Normally the tongue, cheek movements and saliva partly clean the smooth surfaces of the teeth, but brackets reduce this natural cleaning.
The main habits that increase plaque buildup are these:
- Snacking often during the day, especially on sticky and sugary foods.
- Sipping acidic and sugary drinks over a long period.
- Skipping brushing at night or keeping it very short.
- Never cleaning between the teeth and under the wire.
Saliva flow also plays an important part in this balance. Saliva neutralizes acids and carries calcium and phosphate to the enamel. Mouth breathing, drinking little water during the day or taking certain medications can cause dry mouth and increase the effect of plaque. Sharing such situations with your doctor at a check-up appointment helps in planning the right precautions for you.
Gum inflammation and swelling
During braces treatment, redness, bleeding and mild swelling of the gums can be seen, and the most common cause is plaque-related gum inflammation (gingivitis). Plaque that builds up near the edges of the brackets irritates the gum. Bleeding during brushing, tender gums and puffiness along the edges are the typical signs of this picture.
In some people the gum tissue grows somewhat and can extend over the brackets. This generally decreases when hygiene improves; in most cases it also recedes noticeably after the brackets come off. The rare cases thought to be persistent are assessed separately by the doctor. For more information on the causes and prevention of bleeding, you can look at our article on why gums bleed. In adults who have had gum disease before, bringing gum health under control before orthodontic treatment is important.
What is root shortening, and how common is it?
Root shortening (root resorption) is a small amount of tissue loss at the root tip while teeth are being moved, and mild root shortening is quite common in orthodontic treatment. In most patients this shortening is less than a millimeter or very limited; it does not practically affect the function or lifespan of the tooth and generally goes unnoticed.
Marked, advanced root shortening is seen in few patients. The risk is associated with factors such as the length of treatment, the forces applied, root shape, teeth that have had trauma before and individual susceptibility. For this reason orthodontists monitor the roots with X-rays before treatment and, when needed, during treatment. If a problem is found, measures such as pausing the treatment plan or readjusting the forces can be considered. It should also be noted that this issue is related to moving teeth, whether with clear aligners or fixed braces.
Habits that reduce the risks
Good oral care with braces keeps most of the risks that may arise during treatment under control. The basic recommended habits can be summarized as follows:
- Proper brushing: At least twice a day, with fluoride toothpaste, hold the brush at an angle to the upper and lower edges of each bracket.
- Interdental cleaning: Interdental brushes, orthodontic floss threaders or a water flosser help clean under the wire and between the teeth.
- Eating pattern: Have sugary and acidic foods close to main meals; avoid hard and sticky foods, as these can also break brackets.
- Fluoride support: Where your doctor considers it appropriate, a fluoride mouthrinse or a fluoride varnish at the clinic can be used.
- Not skipping check-ups: Regular appointments allow problems to be noticed early.

What is checked at check-ups?
Orthodontic check-ups are done not only to tighten or change the wire but also to monitor oral health. The following are generally assessed at these appointments:
- Whether there is plaque buildup or the beginning of a white spot around the brackets.
- Whether there is bleeding, swelling or overgrowth of the gums.
- Mechanical problems such as a broken or loose bracket or a poking wire.
- Monitoring the condition of the roots with X-rays when considered necessary.
- Reviewing brushing technique and giving the patient feedback.
Check-up intervals vary with the treatment plan; we covered this frequently asked topic in our article on how often braces are tightened. While treatment is under way, it is also recommended to keep up general dentist check-ups and any professional cleanings considered necessary. For general information on the stages of orthodontic treatment, you can see our page on braces treatment.
Do braces harm the teeth?
Orthodontic treatment that is properly planned and carried out with good oral care can be completed without permanent harm to the teeth. Most of the problems referred to as the harms of braces, namely cavities, white spots and gum inflammation, are largely preventable. Effects related to personal susceptibility, such as root shortening, are monitored with regular follow-up. Straightening crowded teeth can also contribute to oral health in the long term by making cleaning easier.
For those considering clear aligners instead of fixed braces, we should note that because aligners can be taken out while eating and brushing, cleaning is easier, but there are rules of their own, such as not having sugary drinks while the aligners are in. At our clinic, clear aligner treatment is provided with Invisalign, and suitability is determined at the exam.

If during treatment you notice frequent gum bleeding, whitening around the brackets, a bad smell or sensitivity, it is appropriate to contact your doctor without waiting for the next check-up. At our polyclinic in Oran, Çankaya, we plan orthodontic treatment together with oral care follow-up and, when needed, gum treatment. You can book an appointment for an assessment through our contact page.
Frequently asked questions
What is done if a cavity develops while wearing braces?
The doctor plans treatment according to the location and size of the cavity. In some cases a filling can be placed while the bracket stays in place, and sometimes the bracket concerned may need to be removed temporarily. Cavities noticed early are generally treated with simpler methods.
Do braces leave permanent damage to the gums?
Plaque-related gum inflammation and swelling mostly recede when hygiene improves and after the brackets come off. In people who keep up regular oral care, no permanent gum problem is expected. In adults who had gum disease beforehand, a gum assessment before treatment is important.
Does root shortening lead to losing the tooth?
The root shortening seen in orthodontic treatment is mostly mild and does not practically affect the function of the tooth. Advanced shortening is seen in few patients. The orthodontist monitors with X-rays when considered necessary and adjusts the treatment plan if needed.
Can I use an electric toothbrush with braces?
Yes, an electric toothbrush can help clean around the brackets. What matters is that the brush makes enough contact with the upper and lower edges of the brackets and that interdental cleaning is not neglected.
How often should I have my teeth cleaned during braces treatment?
The frequency of professional cleaning is recommended by the doctor according to the person's plaque buildup and gum condition. Oral hygiene is assessed at check-up appointments, and a cleaning is planned when considered necessary.
