Can a tooth sink into the gum?
Ankylosis occurs when a tooth fuses to the surrounding bone and slowly begins to sink or submerge into the nearby gum tissue. Normally, small fibers called the periodontal ligament hold a tooth in its socket, but with ankylosis, this connection is absent, and the tooth becomes directly attached to nearby bone.
Do all aspens have catkins?
Each tree is either male or female, and while both male and female aspen produce catkins, only the male catkin has pollen, which is transferred to a female by the wind.
What is a concussed tooth?
Teeth that have received a hard hit, but haven’t been knocked out or broken, are considered “concussed.” These dental concussions can cause teeth to hurt and discolor permanently or temporarily, but normally don’t require emergency treatment, unless black or dark. Dental concussions typically occur with toddlers.

Do poplars have catkins?
A catkin is a spike of flowers of one sex – individual poplar trees have either male or female catkins – so you need both male and female trees in relatively close proximity to make baby poplars. The puffy catkins on my poplar tree (a quaking aspen a.k.a. Populus tremuloides) are probably male.
Do aspen trees get catkins?
What is special about aspen trees?
Aspen is noted for its ability to regenerate vegetatively by shoots and suckers arising along its long lateral roots. Root sprouting results in many genetically identical trees, in aggregate called a “clone”. All the trees in a clone have identical characteristics and share a root structure.
