Gap between crown and gumline?

Hello there,Sorry to hear that you're having this issue.  It is not ideal to have a large gap here, but it is very, very common.  Unfortunately, using a waterpik is something that you should continue to do, indefinitely.  This is will highly prevent food from sitting there long-term and contributing to decay and ultimately implant failure. Good luck and I hope this info helps you.

Thank you for your question regarding a gap in between the crown and gumline. Crowns for an implant should be precisely fitted and normally do not have gaps. The gap should be resolved so that you have as little food impaction as possible. Possibly, the crown needs to be remade and you should discuss this option to eliminate the gap with your dentist. Good luck!

It is not uncommon for more food to collect around the gum line of an implant crown as compared to a natural tooth especially in the molar region, because the implant is narrower right at the gum line than an actual tooth.  It is best to have a good fit to the gum with the the crown restoration so that this can alleviate some of those issues, although it will still be a bit of an issue.  On a positive note, decay does not occur around an implant so you have alleviated one source of failure and water piking has advantages for the health of your entire mouth.

Without a photo or radiograph it is hard to comment.  Implants tend to catch a little more food around them verses a natural tooth since they are narrower than a natural tooth.  If there is a gap that can be closed then I would prefer closing it to avoid catching too much food around the teeth.
