3 extremely dangerous complications of braces

1. Complications of braces Popping the tooth root out of the alveolar bone

This is one of the most serious and worryingharmful effects of braces. Normally, your tooth roots should fit along the axis of the jawbone. However, if the doctor uses too much force, or does not control the force well during thebraces process, the tooth root may be knocked out of this position. In addition, the use of poor quality tools is also a cause of this condition. At that time, the tip of the tooth can completely emerge.

If the force is not well controlled, it will lead to the complication of tooth root dislodging from the bone 

Consequences of tooth root dislodging during braces

The consequences of this complication are very serious. The fix is ​​extremely difficult, the success rate is only about 30%. In the remaining 70% of cases, you will be forced to remove the tooth and replace it with an implant. This is not only costly but also takes a lot of time and effort.

Recognizing signs

For accurate diagnosis, the doctor needs to take a Cone Beam CT scan. However, you can recognize it early at home through some signs:

  • Teeth are crooked inward:You find your teeth naturally crooked, especially when you bite your teeth together.

  • Box occlusion:When you bite back, you cannot see the lower teeth.

  • Feel the tip of the tooth protruding:You can feel a hard lump protruding from the gum above the tooth root. However, this sign can also be due to excessive growth of the alveolar bone, so you need to see a doctor to get an accurate conclusion.

2. Complications of braces: Resorption of tooth roots

Are braces dangerous? Yes, if excessive tooth root resorption occurs. Usually, approx90% of braces cases will have a slight loss at the tip of the tooth, only about 1-2mm.This is a normal phenomenon. However, if the doctor uses too much force, a large portion of the tooth root can be lost. This will seriously affect the longevity of teeth.

In most cases, braces can cause tooth root loss, but to a certain extent

Consequences of tooth root resorption

When tooth roots are shortened, the tooth's chewing ability is significantly reduced. Furthermore, the lifespan of teeth is also greatly reduced. Severely eroded teeth can usually only last about 3-4 years after braces are removed, then they will fall out.

Identification signs

An early sign of this condition is excessive loose teeth. Although teeth often loosen slightly during the braces process, if you feel constant pain or when you press the teeth, you should be suspicious of theharms of braces. To make a sure diagnosis, the doctor will compare full-mouth X-rays (Panorama) orCone Beam CT filmsbefore and after braces to evaluate the degree of shrinkage.

3. Complications of braces: Alveolar bone loss

Alveolar bone is a solid foundation that helps teeth stand.Harmful effects of bracesincorrectly can cause this bone to gradually disappear. The cause of complications may be due to the doctor using too much force, the wrong method of transmitting force, or the patient having poor oral hygiene leading to periodontitis.

Consequences of alveolar bone loss during braces

When the alveolar bone is resorbed, the attachment area of ​​the tooth root is significantly reduced. This causes teeth to become weak, loose and at risk of being lost prematurely. This is one of the dangerouscomplications of braces, directly affecting long-term oral health.

Signs of alveolar bone loss during braces

Alveolar bone loss is a silent complication, difficult to detect with the naked eye. The initial sign is usually a slightly loose tooth. To make an accurate diagnosis, the doctor will need to take an X-ray or CT scan to check bone density and alveolar bone height.

Causes of dangerous complications when wearing braces

According to Dr. Vinh, dangerous complications of braces such as tooth root extrusion, tooth root shrinkage or alveolar bone loss all stem from the doctor's professional mistakes. There are three core causes that Dr. Thai Khac Vinh emphasized:

  • Wrong treatment planning:Doctors cannot determine the safest and most effective way to move teeth. Braces is the process of moving teeth from an old position to a new position, and the doctor must choose the correct safe and convenient route to bring about the best results.

  • Using inappropriate force:The doctor cannot calculate the force and intensity to use. Too much force can dislodge or dissolve the tooth root. On the contrary, if the force is too weak or uneven, the teeth will not move or move too much.

  • Incorrect choice of tools and technology:The doctor may use tools of poor quality or not suitable for your tooth condition. In addition, the lack of modern technology to control force and monitor tooth movement is also a common cause.

The doctor has confirmed that the nature of braces is a process of moving teeth from an old position to a new position. The doctor's task is to answer three important questions to ensure patient safety:

  • Path:Which path is the safest and most convenient for the teeth to move?

  • Force:How much force is needed for the teeth to move safely and stably?

  • Appliances:What appliances should be used and how to achieve the best results?
