Is it really a dot, like in a bullet style, or is it a little black
square in the left margin? The latter is a nonprinting mark that tells
you one or more of the boxes are checked in the Line & Page Breaks tab
of the Format > Paragraph dialog. Look about 3/4 of the way down the
page at http://www.word.mvps.org/FAQs/Formatting/NonPrintChars.htm to
see a description. It will go away when you turn off nonprinting
characters by clicking the ¶ button.

If there really is a bullet (black circle) at the start of the
heading, and it prints, then you've gotten a bullet attached to the
style. In that case, go to the Format > Style task pane, right-click
the Heading 1 style, and choose Modify. In the dialog that appears,
click the Format button in the bottom left and choose Numbering.
Choose the None box and ok back to the document. You may have to
repeat this for Heading 2, or the bullet may have been inherited from
the Heading 1. The other thing you need to do is to go to Tools >
AutoCorrect Options > AutoFormat As You Type, and make sure "Define
styles based on your formatting" is _not_ checked.
