By definition, yes. Periodontal means "around the tooth." Periodontal disease is disease around the tooth. If there are no teeth, there can be no disease around the teeth.
Reptiles and fish both regularly replace their teeth. This way they avoid the problems that mammals can get with dental disease. Old teeth are eliminated before they become diseased, and they are replaced by new teeth.

Having a tooth extracted alone won't straighten other teeth in the mouth. Orthodontists may request certain teeth be extracted for the purpose of making room to straighten teeth using braces, or other orthodontic appliances.

Teeth cannot heal or repair themselves like other parts of the body can. Once teeth are damaged or decayed, they cannot regenerate new tissue to restore their structure. Additionally, teeth do not have the ability to grow back if they are lost or extracted.
32 if she hasn't had any extracted. 28 if she's had her wisdom teeth out.
Yes, cuspid teeth, also known as canine teeth, can come out due to various reasons such as dental trauma, decay, or gum disease. In children, they typically fall out to make way for permanent teeth, but in adults, if they become loose or problematic, they may need to be extracted by a dentist. Regular dental check-ups can help maintain their health and prevent loss.
Out of 32 adult (permanent) teeth, most adults have 28(wisdom teeth extracted), or 24(wisdom teeth and one premolar in each quadrant extracted). Most adults in their 40's have the latter, because it was common to extract the 4 premolars for orthodontia at that time. Most younger adults have 28 teeth. Some adults have all 32. I would say the average adult has 28 teeth.
Wisdom teeth should be extracted when they push and damage the 7th tooth while they grow, also when they develop a cyst or cause an infection, and wisdom teeth are removed if they're causing problems with prosthesis. Here's an interesting video about wisdom tooth extraction.
Losing teeth is not a normal ageing process. It happends because either your teeth are badly broken down from decay and they need to be extracted, because of trauma or gum disease. If you are careful and brush your teeth in the right manner and frequence then your teeth should be able to last for the rest of your life. Obviously they age too which means that their colour might change but you they should still be functional.
