Thanks for your query.
,heart related diseases etc.... can affect the wisdom tooth extraction
You mentioned that you had a baby 14 weeks ago so your baby must be on breast feed,because 6 months after delivery exclusive breast feeding is recommended.
This breast feeding may also affect your wisdom tooth extraction,because after extraction antibiotic and analgesic
coverage is must to prevent infection of the extraction site and to promote the healing.
Antibiotics and pain killers during pregnancy and during breast feeding is not recommended as it can affect the growth and development of your baby.
Extraction of wisdom tooth often ends with complications like pain,bleeding weakness post extraction.
As you the detail about your weight,your weight will not be a problem for wisdom tooth extraction.
Hope this will relive your symptoms.
