Gums (gingival tissues) do like to grow and swell up (become inflamed) in the presence of braces. There are a few different reasons for this to happen. First of all, gum tissues naturally get inflamed in the presence of braces. Braces cause put pressures on the teeth and the gums have to adjust accordingly. This means they fill up with blood. So, the first thing to figure out is, are the gums actually growing over the braces or are they just so swollen that the braces can barely be seen (this is usually the case, but it looks like the gingiva is growing). If this is the case, it will usually resolve over time; however, it also requires diligent cleaning of the gums and teeth to make it return to its natural state. Secondly, sometimes braces worsen a condition that was already there. This condition is hormones. Gums swell up drastically to hormones and when you add tooth movement from braces or Invisalign it sends the gums over the top. This happens to both men and women because of hormonal changes; but, women might notice fluctuations of swelling aligned with their cycle.
The important thing to remember is that you are not alone.
Hope this helps.
My best to you!

The gum overgrowth is usually caused by bacteria that accumulate on the wires. Meticulous oral hygiene after each meal should resolve the problem. If there is a lot of overgrowth, it will subside after wires are removed.
