Why is my tooth loose?
In an adult, a loose tooth means the attachment holding it has been lost or damaged. The commonest reason is advanced periodontitis — bone loss around the root, usually painless until late. The other reasons are trauma, a root fracture, occlusal overload from grinding or a high restoration, and infection at the root tip. Mobility is graded clinically and confirmed with a radiograph; whether the tooth can be saved depends on how much bone is left, not on how it feels.
What a loose tooth usually turns out to be
- Advanced periodontitis with bone loss
- Injury to the tooth or the supporting bone
- Root fracture or a failed root canal
- Occlusal trauma from grinding or a high filling or crown
- An abscess or a cyst around the root
What to do before you are seen
- Do not test the looseness repeatedly with your tongue or fingers
- Eat on the other side and keep the area clean
- Get it assessed promptly — early treatment saves teeth that late treatment cannot
- After an injury, treat it as urgent; timing changes the outcome
This is general guidance and does not replace an examination. Only a clinical examination with radiographs can identify which tooth or tissue is causing your symptom.
When to see us
- Gums that bleed without provocation, or bleeding that has become heavier
- Teeth that feel loose, are drifting, or gaps that are opening up
- Persistent bad breath or taste, gum abscesses, or pus on pressing the gum
Detailed guides on this symptom
How Dentists Treat a Loose Tooth After Facial Trauma
Trauma to the face can disrupt the periodontal ligament and neurovascular supply, causing tooth mobility. This clinical guide explains how dentists assess, reposition, splint, and monitor a loose adult tooth after physical impact to maximise tooth retention.
Occlusal Trauma and Bite Adjustment for Periodontitis
Occlusal trauma occurs when excessive biting forces injure the supporting structures of teeth. When combined with periodontitis, it accelerates bone loss and tooth mobility. Bite adjustment and periodontal therapy stabilise loose teeth and protect long-term oral health.
Gum Recession Caused by Lip or Tongue Piercings
Oral piercings cause significant periodontal trauma, leading to gingival recession, root exposure, and alveolar bone loss. This clinical guide explains anatomical mechanisms, risk factors, staging, mucogingival surgical treatments, postoperative care, and essential prevention strategies.
Alveolar Bone Fracture Repair and Loose Teeth Stabilization
Alveolar bone fractures involve breaks in the tooth-bearing jaw segment, causing tooth mobility and malocclusion. This clinical guide covers emergency reduction, dental splint stabilization, diagnostic imaging, pulp monitoring, complications, and evidence-based post-traumatic recovery protocols.
Addressing Bone Loss Around Teeth
Periodontal disease can lead to bone loss, undermining tooth stability. We explain how we diagnose, manage, and halt bone loss to keep your teeth healthy.
Splinting Mobile Teeth for Stability
Tooth splinting offers stability to mobile teeth affected by gum disease or trauma. We explain how this technique can save your teeth and improve comfort.
Lip Repositioning Surgery for a Gummy Smile
Lip repositioning surgery is a minimally invasive periodontal procedure designed to treat excessive gingival display caused by upper lip hypermobility or mild vertical maxillary excess by restricting muscle pull and narrowing the vestibule.
How Diabetes Affects Gum Health and Healing
Diabetes and gum disease share a complex, bidirectional relationship driven by chronic systemic inflammation. Poor glycaemic control accelerates periodontal bone loss, while periodontal therapy helps improve blood glucose regulation, tissue repair, and long-term oral stability.
Jaw Bone Loss Around Teeth from Periodontitis
Jaw bone loss around teeth results from chronic inflammatory periodontitis destroying the supporting alveolar bone. This evidence-based guide explains biological mechanisms, clinical staging, non-surgical and surgical interventions, diagnostic protocols, and long-term supportive periodontal care to preserve dentition.
Scaling and Root Planing Deep Cleaning Procedure
Scaling and root planing is a non-surgical deep cleaning procedure designed to treat chronic periodontitis. It removes subgingival plaque biofilm, hard calculus, and bacterial endotoxins from tooth root surfaces to arrest active gum disease and prevent bone loss.
Chronic Gingivitis Causes Symptoms and Home Care
Chronic gingivitis is a reversible, biofilm-induced inflammation of the marginal gingiva without alveolar bone loss. Understand its causes, symptoms, diagnostic stages, professional debridement protocols, and evidence-based home care techniques to prevent irreversible periodontitis.
Furcation Involvement and Bone Loss Between Roots
Furcation involvement describes bone loss between the roots of multi-rooted molars caused by advanced periodontal disease. This clinical guide explains its causes, diagnostic staging, surgical and non-surgical therapies, daily maintenance, and red flag symptoms requiring urgent care.
