Common Questions Patients Ask About Dental Implants
Dental implants are considered the gold standard for replacing missing teeth, but it’s completely normal to have questions before starting treatment. Below, we answer the most common questions patients ask us about dental implant treatment.
Why choose a periodontist for dental implant treatment?
Dental implants don’t just replace teeth — they rely on healthy gums and strong bone to succeed long term. That’s why who places your implants matters.
A periodontist is a dentist who has completed several additional years of specialist training focused specifically on:
-
Gums
-
Bone
-
Implant dentistry
-
Prevention of implant complications
This advanced training means a periodontist is uniquely qualified to:
-
Assess bone quality and gum health in detail
-
Manage existing or previous gum disease
-
Carry out complex implant and bone grafting procedures
-
Reduce the risk of long-term implant problems such as infection or bone loss
In short, implants placed by a periodontist are planned not just for today — but for lasting health, stability and success.

What is a dental implant?
A dental implant is a small titanium post that replaces the root of a missing tooth. Once placed, it integrates with the jawbone (a process called osseointegration) and acts as a secure foundation for a crown, bridge, or denture. Titanium has been safely used in medicine for decades, including hip and knee replacements
Are dental implants suitable for everyone?
Dental implants are suitable for most adults in good general health. Treatment is usually recommended once facial growth is complete. Smoking can significantly reduce implant success, and gum disease must be stabilised before treatment. Each case is carefully assessed during your consultation
How do I know if I am a candidate for dental implants?
A thorough assessment is carried out, including clinical examination and X-rays. In some cases, a 3D CBCT scan is required to accurately assess bone volume and identify important anatomical structures. Following this, a personalised treatment plan is provided
Do I need healthy gums before having implants?
Yes. Healthy gums and bone are essential for long-term implant success. Gum disease is one of the leading causes of tooth loss and bone loss. Any active infection or instability must be treated first. Specialist periodontal care can often make implant treatment possible even in complex cases
How long does dental implant treatment take?
In straightforward cases, treatment typically takes 3–6 months from implant placement to final restoration. If additional procedures such as bone grafting are required, treatment may take longer. This phased approach helps ensure long-term success
Does implant surgery hurt?
Implant placement is a minor surgical procedure carried out under local anaesthetic, similar to having a filling. Most patients report less discomfort than a tooth extraction. Post-treatment discomfort is usually mild and easily managed with over-the-counter pain relief
Can I have sedation for implant treatment?
Yes. For anxious patients or longer procedures, options include:
-
Oral sedation
-
Conscious (IV) sedation
Conscious sedation allows you to remain relaxed and comfortable without general anaesthesia, which is only required for very complex cases
How long do dental implants last?
With good oral hygiene and regular professional maintenance, implants can last many years — often decades. Like natural teeth, implant restorations may occasionally require repair or replacement due to normal wear over time
How many teeth can be replaced with implants?
Dental implants can replace:
-
A single tooth
-
Multiple missing teeth
-
A full arch of teeth
Not every missing tooth requires its own implant. Treatment is tailored based on bone quality, bite forces, aesthetics, and function
What causes bone loss after tooth loss?
After a tooth is lost, the surrounding bone naturally shrinks. This happens most rapidly in the first few months. Factors include previous infection, how the tooth was removed, and how long the tooth has been missing. Early implant placement or bone preservation techniques can help reduce bone loss
Do implants help maintain bone health?
Yes. Implants stimulate the jawbone, helping maintain bone density and strength during everyday activities such as chewing and speaking. This is a key advantage over traditional dentures
Are there risks involved with dental implants?
All surgical procedures carry some risk, but complications are rare when implants are carefully planned. Important anatomical structures, such as nerves and sinuses, are identified using imaging to ensure safe placement. Success rates are reported at 97–99% long-term
Can implants be placed next to existing teeth?
Yes, in many cases. However, neighbouring teeth must be healthy. Infections or unusual root shapes may affect implant placement and are carefully assessed during planning
Can I have temporary teeth during implant treatment?
Yes. Temporary teeth can often be provided for appearance and function while implants heal. The need for temporary restorations depends on visibility, function, and individual circumstances
Is there an age limit for dental implants?
There is no upper age limit for dental implants, provided you are in reasonable general health. Age alone is not a barrier to treatment
Can I still have implants if I don’t have enough bone?
Yes. Advanced procedures such as bone grafting and sinus lifts can often rebuild the foundation needed for implants. Specialist teams regularly treat patients successfully even in complex situations
Final thoughts
Dental implant treatment is highly predictable, carefully planned, and tailored to each patient. A consultation is the best way to understand your options and receive personalised advice.
