For patients who think their teeth no longer stand a chance

Before you have all your teeth extracted, find out which ones can stay

Our mission is to keep natural teeth and to build a beautiful, natural smile on them, with as few extractions as possible.

An extraction is permanent. Sometimes it can be avoided.

Keeping your teeth

What conservative dentistry means for you

At D'Institute we start from a simple question: what can we keep? Each tooth is assessed separately, on the X-ray and in the chair, before we talk about extractions.

See how we decide whether a tooth can be kept
  • We assess every tooth. We measure the bone and check the quality of the roots and how much the tooth moves. Only then do we decide what stays.
  • We treat what can be treated. Root canal treatment under the microscope, laser for the gums.
  • We extract only when there is no other way. And we explain why, on your own X-ray.

Consultation

A second opinion before extraction

If you have been advised to have one or more teeth taken out, you can ask another dentist for their view before you decide. It is your right as a patient, set out in the Code of Ethics for dentists in Romania.

  1. You book a consultation and bring your panoramic X-ray, if you have one. If not, we take one at the clinic.

  2. The dentist looks at the X-ray and examines you.

  3. You leave with a clear answer: which teeth can be kept, which cannot, and what options you have.

A second opinion is a regular consultation, charged at the consultation fee in our price list.

The D'Original system

D'Original: a fixed restoration on your own teeth

D'Original is a fixed full-arch restoration supported by your own teeth: a titanium framework with zirconia crowns. You leave on the first day with fixed temporaries, and the final restoration is ready in 5 working days, in eligible cases, after assessment.

  • Efficient chewing on both sides. The restoration is fixed and sits on your teeth. It does not come out.
  • You feel the pressure on your teeth. Your teeth sense pressure through the ligament that holds them in the bone, and the restoration keeps that sensation.
  • You smile without hiding. The teeth look like yours, because under the restoration they really are yours.

When some teeth can no longer be kept, the restoration is supported by your teeth and a few implants. This option is called D'Original Plus.

Dentistry 2.0

A dental lab in the same building

Your dental work is not sent to another city.

The dental technicians work in the same building as the treatment rooms, so a crown or a full arch is tried in, adjusted and finished without you waiting for a courier.

For D'Original, this means adjustments are made on the spot while you are at the clinic, and the final restoration can be ready in 5 working days, in eligible cases, after assessment.

Scanning instead of impressions, digital planning, the microscope and the lab in the building go by one name here: Dentistry 2.0.

They are the tools that let us treat a tooth instead of taking it out.
