Hello! Just had a go at an MMI question and I would greatly appreciate some feedback on this

I didn't quite time myself because I am focusing more on the content right now.
A 63-year-old man who is a lifelong smoker and a 23-year-old pregnant lady both need dental implants, but there is only one set of dental implants. Who should get the dental implants?
- My decision will not be based upon the patient's personal background or any pre-conceived notions or bias. It will be based on the severity and urgency of the condition, as well as age.
- Firstly, the severity of the condition is to be considered. The person that is experiencing more pain while possibly eating or is having troubling ingesting should be prioritised. This doesn't only cause them pain, but can present side-effects in the form of indigestion or not receiving proper nutrition which can possibly hinder the person's ability to engage in other tasks. For example, if the 23 y.o pregnant lady isn't able to eat a sufficient amount of food or is experiencing great pain (on top of her pregnancy), then it can have a domino effect on the foetus inside her who also needs nutrition.
- Secondly, age is another important factor. For example, due to his age, the 63 year old man has used his set of teeth for a longer period and may have a weaker set of teeth or possibly more missing teeth compared to the lady, thus it would be important to prioritise him.
- Thirdly, it would be important to conduct clinical examinations to determine whether there are possibly any other underlying or additional issues regarding the missing tooth/teeth and one person may be suffering from more dental issues than the other
- My decision on who to the give the dental implant will be made based on severity, age and underlying issues. The person suffering from the issue of missing tooth/teeth to a greater degree, will be prioritised

In these types of questions, is it necessary to give a solid answer on who actually receives it? Also, I know we can't assume, but is it still safe to state how one's age could mean that their teeth are weaker?
