What is peri-implantitis?

Peri-implantitis is an infectious disease that causes inflammation of the gum and the bone structure around a dental implant. Chronic inflammation causes bone loss, which can lead to a loose implant that could eventually fall out. The risk of inflammation and peri-implantitis is much higher with implants in comparison with natural teeth, as the implant attachments are more fragile. If the gums are loose around the implants, harmful bacteria can grow below the gums causing bone loss.

Causes of peri-implantitis

Since an implant cannot attach as easily to the gums as natural teeth, the risk of inflammation and in the end peri-implantitis, is much higher. The gum stays loose around the implant and therefore harmful bacteria can nest more easily in the gum. This can not only cause inflammation but also bone loss. Of all implant patients, more than 40% are affected by inflammations around the implant, known as peri-implantitis. Some of the risk factors are:
  • Smoking
  • Periodontitis
  • Genetic sensitivity to both
  • Diabetes


How you can recognise peri-implantitis? If you have implants and one or more of the following symptoms, we advise you to contact your treating dentist or oral hygienist as soon as possible.

  • Bone loss around implant
  • Bleeding gums
  • Redness and swelling of the mucosa
  • Pus formation
  • Pain around a possibly loose implant

Peri-implantitis is a multifactorial disorder and bacteria plays a huge role, but most likely not the main cause of developing this disease. Bacteria found in peri-implantary pockets can also be found with stable implants.


Untreated peri-implantitis can have nasty consequences. One of these consequences is bone loss, which can result in losing your implant. It is very important to treat this problem fast and efficiently. The TOOTH-guideline of Dr. Blijdorp will give you the information you need.

How can you prevent peri-implantitis?

bluem® Oral Gel is developed to help prevent peri-implantitis. bluem® Oral Gel:

  • Normalises and controls harmful bacteria in the peri-implant pockets
  • Accelerates the wound healing process after implants
  • Accelerates the healing of bleeding gums

In order to treat or even prevent peri-implantitis, Dr. Peter Blijdorp recommends brushing your teeth twice a day with bluem® toothpaste and rinsing twice a day with bluem® alcohol and fluoride-free mouthwash. After brushing and rinsing, apply bluem® oral gel one or two times a day below the implant (or where needed) and leave the gel as long as possible on the spot. Use the Terumo syringes to apply the gel on the hard-to-reach areas in the mouth. See your dentist and ask for bluem® to treat Peri-implantitis!

Frequently asked questions about peri-implantitis

Can you have a full peri-implantitis treatment in one day?
This is possible, but it is still in its experimental phase. There is not a lot known about the success of these “one-day” treatments. The more time implants get to grow in a strong position, the smaller the risks problems will occur.
Can you make a bridge on an implant and your own tooth?
This is possible, but not advisable. The constructions often get destroyed. This has got to do with your own tooth which is “movable” and an implant isn’t. Because of this fact all pressure is on the implant which can result in breakage of the implant itself.
Can you place a new implant when a previous implant has failed?

This should be possible. It depends why the old implant failed. If the cause is treatable, a new implant can be placed when the bone is healed.
