Hello,
About 1.5 weeks ago, we took Dudley in to the free nail/teeth clinic in my area for the first time. They discovered he has severe malocclusion to his incisor teeth. She trimmed off probably 1.5cm of tooth, and since then he has been eating much more and seems happier! Poor little guy 
She told us he would need to be seen often, which I am totally fine with doing..
I just wanted some advice for owners who have also dealt with malocclusion. The vet said it looked like he was born this way.
1) How often will his teeth need to be trimmed? The free clinics are twice a month
2) How to assist in making sure his teeth do not get out of control again (Already have unlimited hay and willow tree sticks)
3) How can I check my other bunnies teeth? She was not able to make it to the clinic in November. I want to check her teeth to see if they will need to be done at the end of December as well, but she will not let me hold her properly in order for me to check. She seems to be eating a lot of hay, and her bites seem relatively even and smoothly cut, but I worry.
Any advice/input would be greatly appreciated
