While a loose baby tooth is perfectly normal, a loose adult tooth is something to be concerned about. Painful and unpleasant, a loose permanent tooth may fall out, need extracting, or cause serious bite problems. This can all be avoided, but it is imperative that you seek professional dental care as soon as you notice that one or more of your teeth are loose.

Causes of Loose Teeth

There are many reasons why an adult tooth may become loose. The most common cause is advanced periodontal disease, also known as periodontitis. Periodontal disease is a bacterial infection that affects the gums and bone supporting your teeth. As the infection progresses, it destroys the bone and ligaments that hold your teeth in place, causing them to become loose.

Other causes of loose teeth include:

• Trauma or injury to the mouth
• Bruxism (tooth grinding or clenching)
• Osteoporosis
• Pregnancy (due to hormonal changes)
• Certain medications

Bite Problems Associated with Loose Teeth

When teeth become loose, they can shift out of position, leading to bite problems such as:

• Malocclusion (misaligned bite)
• TMJ disorders
• Difficulty chewing or speaking
• Increased risk of tooth loss

If you have loose teeth and bite problems, it's important to see your dentist or periodontist right away. Early treatment can help save your teeth and prevent further damage.
