If you’ve undergone, or are currently considering, full mouth dental implant surgery, you may have heard about the infamous “Mr Lumpy” - a temporary lump that can appear on the roof of the mouth following surgery. It’s a harmless and expected part of the healing process, caused by where the surgical guide pins were placed during implant placement. In this blog, we’ll explore why it happens, how to help it heal quickly, and when it’s time to reach out for reassurance.
Why Does The Lump Appear?
During your surgery, we use a fully guided approach to ensure every implant is placed with absolute precision. To achieve this, small stabilising pins are used to secure a surgical guide in your mouth. This guide acts like a roadmap, allowing our team to place every implant exactly where it should be - down to fractions of a millimetre.
This accuracy is essential for your long-term comfort, function, and implant success. After the guide and pins are removed, some patients notice a small, tender lump at the roof of their mouth - affectionately nicknamed “Mr Lumpy”.
Like a bruise you may get on your arm, the same thing can happen in your mouth after surgery. It’s nothing to worry about, and it doesn’t necessarily mean anything has gone wrong - it’s simply part of your body’s natural healing response.
How Long Will It Last?
The mouth generally heals very quickly. For most patients, the lump starts to shrink within a few days, and when left alone, should disappear completely in a week or two.
It’s important to note that everyone’s healing timeline is different, but as long as you follow your post-surgery care instructions and the advice of your clinician, “Mr Lumpy” should exit on his own.
When To Contact Us
If the lump becomes unusually painful, increases in size, or you notice any abnormal bleeding or changes that concern you, reach out to the team. In almost every case, it’s completely harmless and will resolve naturally - but of course, we’re always here for help and reassurance.
The Bottom Line
At 21D, we use guided implant surgery because it delivers the highest levels of accuracy and precision. We recommend you:
- Follow the aftercare guidance provided by your clinician
- Keep the area clean using your prescribed mouthwash and gentle rinsing techniques
- Eat soft foods and stay hydrated
- Don’t disturb it by prodding and poking - this can delay healing or cause irritation
- Get in touch with us, should you ever feel worried or unsure what you’re feeling
Our team is always here to reassure you, check your healing, and ensure everything is progressing exactly as it should!
