Can I live without canines?

Question from Yasmine, an internet user.

Hello,
I’m 18 years old and I have impacted canines, but I do not want to undergo the surgery.
So, I need your advice.
Can I live without canines?

.

Response

Good morning Yasmine,

I apologize for taking a few days to answer your question. You have an excellent question that is worth thinking about.

Can we live without canines?

The answer is yes, we can live without canines. Except that you are not asking the right question.

You mention having to undergo a surgery which would be done to expose and ligature the impacted canine for an orthodontic traction. Yet, you refuse the surgery. This means that your canine will stay impacted.

The right question

The right question to ask is:

What are the risks associated with keeping one or more impacted canines?

First, I will show you a few examples of occlusion without permanent canines. Then I will illustrate a few examples of damage that an impacted canine can cause.

Occlusion without canine(s)

Case #1 and case #2: canine #13 was impacted and ankylosed. Case #3: Agenesis of 2 permanent canines #13 and #23.

.

Cases #1 and #2 each had their canine #13 impacted and ankylosed, that is fused to the bone. It was thus impossible to proceed with their orthodontic traction. The removal of the impacted tooth was necessary. The patients were told that the removal of 3 premolars (#24, #34 and #44 for case #1 and #24, #35 and #45 for case #2) would be necessary to obtain an ideal occlusion. The Xs represent the spot where the canines would be if they existed. The first premolars #14 and #24 are identified. The replacement of canines by first premolars allows the patient to obtain an acceptable esthetic and functional result.

Ankylosed canine

The picture on the left represents the ankylosed canine of case #2. The tooth crown is delimited by the dotted line. No space was visible between the enamel and the bone, confirming the ankylosis (fusion to the bone) of the tooth. The removal was the only possible option.

Case #3 presented agenesis of the permanent upper canines (he never had them). Two premolars had to be extracted in the mandibular arch.

These cases thus show that it is possible to live without canines and have a functional occlusion.

Risks associated with an impacted canine

You must know that if you do not do anything and you keep your impacted canine, you are taking risks.

1- Formation of a cyst of the follicular envelope

Dentigerous or follicular cyst. The 13 indicates the permanent canine. The “C” indicates the primary canine. The dotted white line indicates the extent of the cyst.

A chronic apical lesion of the primary canine facilitated the development of a follicular cyst and the exaggerated movement of the permanent tooth #13.

This exaggerated upward and forward movement of the impacted canine makes the de-impaction treatment more difficult and longer.

 

2- Radicular resorption of permanent incisors

Resorption of permanent central incisors caused by two impacted canines

.

Incisors can suffer from resorption of their root. Note that the central incisors lost at least 50% of their length because of the impacted canines. Figuratively, we could say that there was a collision between the canine and the root of the incisor and the root “disappeared”.

In that case, we decided to extract the impacted canines, because it would have been impossible to perform the traction of these canines without causing more damage to the roots of the incisors.

Resorption of permanent lateral incisors caused by impacted canines

This patient was lucky, because sometimes, one or more incisors need to be extracted like in this other case shown on the right.

 

3- Ankylosis of the impacted tooth

This problem was shown and discussed in the previous section. In such case, the removal of the ankylosed tooth is part of the solution.

.

 

Conclusion

.

This is just a brief summary of what can happen with an impacted canine. I did not describe every risk. It would be too long doing so.

Going back to your case, I want to understand that you do not want any surgery. But you will have to assume the risks and complications which will inevitably occur because of your decision.

Between two evils, you have to choose the lesser one. Undergoing a surgery to ligature an impacted canine is much better than any risks that you could face if you do not do anything.

You can live without canines if you do not have them, but you should not live with an impacted canine if you have any.

Think about it and make the right decision.

  1. Excellent description of the choices in your example cases and the problems of NOT identifying and correcting impactions. The correct final statement!

  2. The risk of developing pathological conditions as a result of retention of an impacted tooth is low, with the exception of decay/resorption of the roots of adjacent teeth. It is often said that an impacted tooth may be asymptomatic, but that does not mean that they will remain that way!
    As an Oral and Maxillofacial Surgeon who routinely removes impacted teeth, I do suggest removal of impacted cuspids. Tiis advice is always tempered with a recognition of the risks that may be associated with the removal of the tooth/teeth. Impacted cuspids can be some of the most difficult teeth to remove and can give riise to issues such as oro-nasal or oro-antral fistula. Surgical exposure and application of orthodontic traction is not always an option and will depend on the location of the tooth in the alveolar bone. It is always best to discuss all risks, complications and benefits with an Oral and Maxillofacial Surgeon before making a final decision over management of an impacted tooth, cuspid or otherwise.

    1. Thank dr McCann

      I think case #2 “radicular resorption of permanent incisors” and case #3 “ankylosed canine” are exemple where surgical exposure and traction is NOT an option.

      Best regards

    If canines are burried in the palate and if the patient refuses the treatmet, what is the patient supposed to expect in the future regarding his/her teeth and faciual struture

    1. I think this page is very clear on the risk associated with impacted canines: follicular cyst, root resorption of the adjacents teeth which will lead to tooth loss.

      A parents that would refuse the treatment of an impacted canine of his child will have to live with the full responsibility of damage that may occur in the development of the dentition.

      Like I said:

      You can live without canines if you do not have them, but you should not live with an impacted canine if you have any.

    I have an impacted canine upper front jaw. I also have braces, my oral surgeon stated I should get the impacted canine remove, once my ortho start moving teeth, my front won’t get damage and possibly losing them. So I had the surgery done two days ago, my surgeon only remove half of my impacted canine. The other half won’t move. The surgeon kept pulling but it won’t move. So he decided to leave the half in.
    He said I should be fine, the piece he remove was near my front teeth. I should be fine when my ortho start moving teeth.
    My question is it safe to leave half of an impacted canine in????

    1. It is possible that your canine was ankylosed like the the picture in the left. However, a skilled oral surgeon should be able to remove it.

      If a part of the root is left in place, I hope it will not jeopardize the root of adjacnet teeth as they are moved to close the space of the extracted canine.

      There is situation where it is indicated to partial odontectomy like in the removal of an impacted 3rd molar.

      I would recommend that your dentist or orthodontist follow up with panogram in 6 and 12 months to make sure it remain safe.

      I have one question. How the orthodontist the asymmetry that is created by the extraction of 1 tooth?

    Hi, my daughter is 12 yrs and previously she had her upper premolars extracted to pave way for the canines which were stuck in. Then yesterday when she was being extracted the lower premolars to balance the top, one of the canine was extracted by mistake and her dentist advised to remove the other canine to balance instead of the premolars. Now my daughter has upper canines and no lower canines will it have any negative impact on her?

    1. Oupps!
      This is a major mistake. I would not fix a mistake by doing a 2nd mistake. Personnaly, I would manage mechanics, keep the other canine and extract the 1st premolar. Did you take action against the dentist who extract the wrong tooth?
      Having said that, it could be a good solution to extract the other canine, but chances that I would not do that.

  6. Barbara Gar says:

    My 11-year old daughter has just been diagnosed with “class II division malocclusion on a mild skeletal II base complicated by (1) diminutive UL2 and UR2; (2) Impacted UL3 and UR3 with possible cystic change and associated root resorption; (3) retained EDC/CDE (both upper/lower); and (4) upper arch crowding.

    We are awaiting further test (on cystic change/root resorption) but initial recommended treatment is to either remove the two diminutive incisors (and shape the canine to look like incisors) or to remove the two canines.

    Reading your article has reassured me that removing the canines can be the right choice (I had previously only come across removal of premolars in orthodontic treatment) but I’d really welcome your thoughts on these options. In particular the two concerns I have are: with the first option wouldn’t the ‘shaping as incisors’ risk compromising the robustness of the teeth? And wouldn’t either of these approach risk leaving gaps between the incisor/canine group and the molar/premolar group (I understand it can be difficult to move molars/premolars forward).

    1. Bonsoir,

      If the lateral incisors are smaller than normal and in a peg shape, it could be a good choice to revome the lateral incisors and do the substition with the canine when a patient has a class II relationship.It is feasible to make the substition without leaving gap. Particularly if the patient is class II.

      However, your orthodontist should discuss with you the possibility of regain a class I molar relationship and not proceed to extraction.

      It is very unlikely that I would plan extraction of the permanent canine in a 11 years old patient.

      My final recommendation is to remove the deciduous canine  and reassess after 6 months. Often time, maxillary expansion AND extraction of deciduous canine is effective in interception of impacted canine. I would delay as much as possible the extraction of any permanent teeth.

  7. Monika Meher says:

    I’ve permanent canine teeth inside my upper jaw. Doctors said they have to be removed because of which I got a gap.between my two incisors. Today I went to the hospital and doctor tried to remove the tooth but he couldn’t as they are difficult to extract.. he somehow extracted two pieces of one canine but not completely. The procedure was so painful. Now I don’t want to continue with that. I just want to kmow that whether me of nor continuing with the further surgery make any complications?

    1. I would like to know if it was an oral surgeon who tried the extraction. It is very unusual.
