Choosing a prosthetic solution should never be random. A bridge, a crown, and an implant may look similar at the end of treatment, but they differ significantly in indications, impact on adjacent teeth and bone, and long-term cost-effectiveness. Below is a practical guide to help you understand the differences and prepare for your consultation.
Dental Bridge – A Classic Solution with Limitations
What Is a Bridge?
A dental bridge is a fixed restoration used to replace one or more missing teeth. It is supported by adjacent teeth, which are prepared (filed down) and covered with crowns. Between them is a pontic — an artificial tooth filling the gap.
When Does a Bridge Make Sense?
- Adjacent teeth already require crowns (e.g., after root canal treatment or with extensive damage)
- One or two missing teeth
- Contraindications to implant placement (e.g., uncontrolled diabetes, jaw radiotherapy, intravenous bisphosphonates)
- Significant bone loss when the patient declines bone augmentation
- Time constraints — bridges are typically completed within 2–3 weeks
Disadvantages of a Bridge
- Preparation of healthy teeth — irreversible and the biggest drawback
- Risk to abutment teeth — failure of one support tooth affects the entire bridge
- Bone loss under the pontic — the bone is not stimulated and may gradually resorb
- More demanding hygiene — requires additional tools (superfloss, interdental brushes, irrigator)
Longevity: 10–15 years on average
Cost: typically PLN 2,500–4,000 (3-unit bridge)
Implant with Crown – The Gold Standard
Why Are Implants Often the First Choice?
- No damage to healthy neighbouring teeth
- Prevents bone loss — chewing forces stimulate the bone
- High durability — can last for many years with proper hygiene
- Excellent function — chewing feels close to a natural tooth
- Hygiene similar to natural teeth
When Is an Implant the Best Option?
- Single missing tooth with healthy adjacent teeth
- Multiple missing teeth (single implants or implant-supported bridges)
- Desire to preserve bone and choose a long-term solution
- Priority: comfort, stability, aesthetics
Limitations of Implants
- Medical contraindications (e.g., uncontrolled diabetes, jaw radiotherapy, IV bisphosphonates, pregnancy)
- Insufficient bone — may require augmentation (additional time and cost)
- Treatment time — typically 3–6 months from placement to final crown
- Cost — typically PLN 4,000–7,000 (implant + crown)
Crown on a Natural Tooth
What Is a Crown?
A crown is a prosthetic “cap” placed over a prepared tooth to restore its shape and function. It does not replace a missing tooth but strengthens a tooth that remains in the mouth.
When Is a Crown Indicated?
- Severely damaged teeth (too large for a filling)
- Teeth after root canal treatment
- Cracked teeth
- Severe enamel wear (e.g., bruxism, acid reflux)
Types of Crowns
- Porcelain-fused-to-metal — PLN 800–1,500 (durable, moderate aesthetics)
- Zirconia — PLN 1,500–2,500 (high aesthetics and strength)
Longevity: 10–15 years on average
Important: a crown does not replace a missing tooth.
Comparison Overview
Bridge
Indication: 1–2 missing teeth; abutments require crowns
Affects healthy teeth: Yes
Time: 2–3 weeks
Cost: PLN 2,500–4,000
Longevity: 10–15 years
Bone impact: Bone loss in gap
Hygiene: More demanding
Implant + Crown
Indication: Missing tooth; healthy neighbours
Affects healthy teeth: No
Time: 3–6 months
Cost: PLN 4,000–7,000
Longevity: Very high
Bone impact: Preserves bone
Hygiene: Like natural tooth
Crown
Indication: Tooth present but weakened
Affects healthy teeth: Only treated tooth
Time: 2–3 weeks
Cost: PLN 800–2,500
Longevity: 10–15 years
Bone impact: Not applicable
Hygiene: Like natural tooth
How to Choose? Ask Yourself These 5 Questions
- What is the condition of adjacent teeth?
- Healthy → implant
- Severely damaged → bridge
- Tooth present but weakened → crown
- What is the condition of the bone?
- Sufficient → implant
- Reduced → augmentation + implant or bridge
- What is your budget?
- Faster and lower initial cost → bridge
- Long-term investment → implant
- Strengthening existing tooth → crown
- How much time do you have?
- 2–3 weeks → bridge or crown
- 3–6 months → implant
- Are there medical contraindications?
- Certain systemic conditions may favour a bridge
Common Mistakes
- Delaying treatment — missing teeth accelerate bone loss
- Choosing the cheapest option without long-term analysis
- Ignoring the impact on adjacent healthy teeth
The Decision-Making Process
Step 1: Consultation — examination, often CBCT imaging
Step 2: Treatment plan — comparison of options (advantages, disadvantages, cost, time)
Step 3: Decision — consider taking time or seeking a second opinion
Step 4: Treatment — scheduling and performing the procedure
Summary
A bridge is appropriate when adjacent teeth already require crowns or when implant placement is not possible. An implant is the most natural-like solution — it preserves bone and does not require grinding healthy teeth. A crown is used to strengthen a tooth that is still present.
