Risks and benefits of dental implant
Informed by recognized medical guidance
Overview
A dental implant is a small metal post, usually made of titanium, that is placed into your jawbone to replace a missing tooth. It acts like an artificial tooth root and holds a crown (a false tooth) in place.
Key facts
- Dental implants can improve your appearance and ability to chew and speak.
- The success rate for dental implants is high, often over 95%.
- Possible risks include infection, nerve damage, and implant failure.
- Implants require good oral hygiene and regular dental check-ups to last long.
- Not everyone is a suitable candidate; your dentist will assess your jawbone health and overall health.
Yes, dental implants are a common and widely used treatment for replacing missing teeth. Millions of people worldwide have them.
Dental implants are for adults who have lost one or more teeth due to injury, decay, or gum disease. You need to have healthy gums and enough jawbone to support the implant.
Symptoms
- Sudden, severe pain after the implant procedure
- Difficulty breathing or swallowing
- Signs of a severe allergic reaction (e.g., hives, swelling of face or tongue)
- ⚠Signs of infection: fever, persistent redness, swelling, or pus around the implant
- ⚠The implant feels loose or moves after the first few days
- ⚠Numbness or tingling that does not go away after the local anesthesia wears off
- ⚠Bleeding that does not stop with gentle pressure
Common symptoms
- After the procedure, some swelling, bruising, and mild discomfort are normal and usually improve in a few days.
Symptoms in children
- Dental implants are generally not recommended for children because their jawbones are still growing.
Symptoms in older adults
- Older adults can get implants if they have good overall health and enough bone. Healing may take slightly longer.
Causes
Main causes
- Tooth loss from decay, gum disease, or injury is the main reason people get implants.
- Implant complications can be caused by poor oral hygiene, infection, smoking, or too much pressure on the implant.
Risk factors
- Smoking or using tobacco products
- Poor oral hygiene
- Uncontrolled diabetes
- Grinding or clenching your teeth (bruxism)
- Weakened immune system
- Certain medications, such as those that affect bone healing
When to see a doctor
See a doctor urgently if:
- If you have signs of infection (fever, pus, spreading redness) after the implant placement
- If the implant feels loose or falls out
- If you have severe pain that does not improve with over-the-counter pain relief
Book a routine appointment if:
- Regular dental check-ups every 6 months to monitor your implant and overall oral health
- Before getting an implant, a consultation with a dentist or oral surgeon to see if you are a candidate
Diagnosis
Before an implant, your dentist or oral surgeon will examine your mouth, review your medical history, and take X-rays or a 3D scan (cone beam CT) to check your jawbone and plan the placement.
Tests that may be done
- Dental X-rays or a cone beam CT scan to see the shape and density of your jawbone
- A comprehensive oral exam to check for gum disease and other issues
- Sometimes a bite test to see how your teeth come together
What to expect at your appointment
The diagnosis process for implant complications may involve an examination, X-rays, and checking for infection or loose parts. Your dentist will explain the problem and discuss treatment options.
Treatment
Dental implant treatment involves a surgical procedure to place the implant into the jawbone. After healing (osseointegration), an abutment and crown are attached. If a complication occurs, treatment may include antibiotics, adjustments, or occasionally removal of the implant.
Self-care at home
- Keep the implant and surrounding teeth clean by brushing twice a day and flossing daily.
- Avoid chewing on hard foods or ice near the implant during healing.
- Rinse with a mild saltwater solution (half teaspoon salt in a glass of warm water) gently to keep the area clean.
- Stop smoking to improve healing and reduce the risk of failure.
Medical treatments
If an implant becomes infected (peri-implantitis), your dentist may clean the area around it and prescribe antibiotics. If the implant is loose, it might need to be removed and replaced after the area heals. For pain, over-the-counter pain relievers are usually enough, but always ask your dentist or pharmacist for advice.
When is surgery considered?
Surgery is required to place the implant into the jawbone. If there is not enough bone, a bone graft procedure may be needed before or during implant placement.
Living with this condition
Most people with dental implants can eat, speak, and smile normally. You may need to get used to the feeling of the implant, but it should feel like a natural tooth. Good oral hygiene is essential to keep the implant healthy.
Lifestyle tips
- Brush and floss like you would with natural teeth.
- Visit your dentist regularly for check-ups and professional cleanings.
- Avoid biting on very hard objects, like ice or fingernails.
- If you grind your teeth, ask your dentist about a night guard to protect the implant.
Diet and exercise
You can eat most foods with an implant, but avoid very hard or sticky foods right after placement. After healing, a normal diet is fine. Exercise is not affected.
Mental health and emotional wellbeing
Losing a tooth can affect your confidence. Implants often help people feel better about their smile and appearance. If you feel self-conscious or anxious, talk to your dentist or a counsellor.
Prevention
While tooth loss itself may not always be preventable, you can reduce the risk of implant complications by maintaining excellent oral hygiene, not smoking, and attending regular dental check-ups. Following your dentist's post-surgery instructions carefully also helps.
Vaccines
Not applicable.
Screening programmes
There are no routine screening tests for dental implant complications. However, regular dental visits allow your dentist to check the implant and surrounding tissues.
Complications
If left untreated
- Infection around the implant (peri-implantitis) can damage the bone and cause the implant to fail.
- Nerve damage may lead to numbness or tingling in your lip, chin, or gums.
- Implant loosening or fracture may require removal.
- Sinus problems if an implant in the upper jaw protrudes into the sinus cavity.
Long-term outlook
The outlook is very good for most people. Dental implants have a high success rate and can last many years, even a lifetime, with proper care. Even if a complication occurs, many issues can be treated successfully. Staying in close contact with your dentist is key.
