What you'll find below is reliable, up-to-date knowledge about the basic treatment options in modern dentistry – gathered in one place, in plain language.

I want this article to shed light on the topic: to show what types of implants and crowns exist, when additional procedures are needed (e.g. bone grafts), what gum disease can change, and in what situations a responsible doctor should slow down rather than "do everything at once".

The goal isn't for you to diagnose yourself after reading this, but to better understand what to discuss with your dentist and what to ask clinics – in your own country or abroad.

Crowns – where to even begin?

Before the word "crowns" is even mentioned, one question needs to be answered: does this tooth still make sense to save. A crown doesn't treat decay or gum disease – it covers them. That's why an honest dentist will deal with the condition of the tooth and surrounding tissue first, and only then think about a crown.

Crowns typically come into play when:

• The tooth is heavily damaged by decay or cracking
• After root canal treatment the walls are so weakened that a regular filling would be risky
• The shape or colour of a tooth needs improving and can't be nicely restored with a filling or veneer

What needs to be treated BEFORE a crown is fitted

Before a tooth gets a crown, you should:

• Remove decay – if there's active decay in the tooth, it needs to be cleaned out and the tooth core rebuilt (sometimes with a post). A crown cannot be placed on a "rotten" tooth
• Do root canal treatment if needed – a tooth with an affected nerve, pain symptoms, abscess or deep inflammation usually requires root canal treatment before a crown
• Sort out the gums – with active gum disease (bleeding, deep pockets, inflammation), the periodontium is treated first. A crown placed on a tooth surrounded by diseased gums has a much worse prognosis
• Ensure a "clean situation" around the tooth – if decay reaches below the gum line, clinical crown lengthening is sometimes needed to make a sealed crown possible at all

Single crowns vs. connected crowns (bridges)

A crown can work "solo" or be connected with others in a bridge.

Single crown:

• Used when the tooth is present but weakened (large filling, crack, after root canal)
• Covers only that one tooth, easier to replace, hygiene is simpler

Connected crowns (bridge):

• Several crowns permanently joined together
• Can be on natural teeth or on implants
• Allows a missing tooth to be replaced, but grinding down healthy teeth and more difficult hygiene are the price of this solution

When someone proposes "crowns for everything"

• Why specifically these teeth need to be ground down – are they really that damaged?
• Were alternatives discussed (fillings, veneers, orthodontics)?
• What about the gums – was there periodontal diagnostics?
• How will hygiene around the crowns/bridges look and who will teach you?

Implants – when do they make sense, and when to slow down

An implant is not "a screw inserted into any old bone", but a replacement for a tooth root that needs to fuse with the bone and transfer chewing forces for years. It's a very good solution, but only when the bone, gums and general health give it a real chance of lasting.

Implants are most often proposed when:

• One tooth is missing and you don't want to grind down adjacent teeth for a bridge
• Several teeth are missing and a denture is uncomfortable
• All teeth are missing and the patient wants a more stable solution than a classic denture

What needs to be checked before deciding on implants

• Condition of the periodontium (gums and bone) – with active gum disease, the periodontium is treated first
• Quantity and quality of bone based on X-ray / CBCT
• General medical history – diabetes, smoking, bruxism, medications, past illnesses
• Hygiene level and willingness to care for implants

How the implant treatment process works

In simplified form:

1. Consultation and plan – examination, imaging, discussion of alternatives
2. Preparation of the mouth – treating decay, root canals, gums, extracting teeth without prognosis
3. Any additional procedures – bone grafts, sinus lift, gum procedures
4. Implant placement – then healing and integration time with the bone
5. Prosthetic component – crown on implant, bridge, implant-supported denture

Implant with crown, bridge, denture

For one missing tooth:

• Implant with crown – doesn't touch adjacent teeth, better maintains bone, but requires surgery and time
• Bridge on natural teeth – faster, no surgery, but at the cost of grinding down neighbours
• Small removable denture – rather as a temporary solution or for larger gaps

For many missing teeth, bridges on implants and snap-on dentures come into play.

When to be careful with implants

• Active, untreated gum disease / large bone loss
• Severe, poorly controlled general medical conditions
• Heavy smoking, bruxism, very poor hygiene

Bone – where does "lack of bone" come from

Bone around teeth most often deteriorates for two reasons: gum disease (periodontitis) and long-term tooth loss. In periodontal disease, inflammation destroys the ligaments and bone holding the teeth. When a tooth is extracted and nothing replaces it, the bone in that area stops being loaded and the body gradually starts to "reabsorb" it.

Bone loss can also result from trauma – a road accident, a blow, a fall, a jaw fracture. Such trauma can damage both the tooth and the surrounding bone.

That's why someone who has been without teeth for years, or after a serious accident, may have very narrow, low bone – cheeks "cave in", dentures don't hold well, teeth become loose.

When a bone graft / augmentation is needed

Not every implant requires a graft, but an implant must have sufficient height and width of bone. When a CT scan shows there isn't enough bone, the doctor may propose:

• Filling the gap after extraction (socket preservation)
• Widening the bone (ridge augmentation)
• Raising the sinus floor (sinus lift) in the lateral sections of the upper jaw

The material can be the patient's own bone, donor material or synthetic. After a larger graft you usually wait several months; with small defects it's sometimes possible to combine the implant with minor augmentation in one procedure.

Does "lack of bone" always mean nothing can be done?

No. Sometimes it means:

• A need for a graft / sinus lift
• Changing the plan (different number/positioning of implants)
• Choosing a denture instead of implants in extreme situations

Gum surgery – what's the point of all these "cuts"

Gums affect both aesthetics and the durability of treatment. Sometimes, for a crown or implant to make sense, the conditions in the soft tissue and bone need to be improved – not just "fit a nice tooth".

Clinical crown lengthening

Used when decay, cracking or the edge of an old filling reaches too deep below the gum line and it's technically impossible to make a sealed crown or filling. The procedure involves moving the gum back (sometimes with slight bone correction) so that more of the healthy part of the tooth is visible and accessible for restoration.

Aesthetic procedures for "gummy smile" and uneven gums

The goal is to even out the gum line and improve smile proportions. Often it's not enough to just "trim" the gums – the bone also needs gentle correction for the result to be stable and healthy.

Gum grafts / gum thickening

When gums are receding or the gum around teeth and implants is very thin and delicate, soft tissue grafting can be performed. Such a procedure:

• Protects the necks of teeth and implants
• Reduces sensitivity
• Improves aesthetics (less "long teeth", less visible metal)

Why this matters with implants and crowns

With implants, healthy thick gum helps maintain stability and reduces the risk of periimplantitis and exposure of metal components. With crowns on natural teeth, a well-planned gum line allows crown margins to be placed where they don't irritate tissue and can be properly cleaned.

What to discuss with your dentist before major treatment

Red flags in clinic offers

• "Crown / implant package for everyone" without thorough diagnostics and discussion of your situation
• Proposal to grind down many healthy teeth purely for a "Hollywood smile" effect
• No interest in your general health, medications, habits
• Promises of "zero risk", "teeth in 24 hours for everyone" without mentioning possible complications
• No discussion of hygiene and check-ups after treatment – as if the topic is closed once crowns/implants are fitted
